congruent
m21 +m22 = 180°
supplementary
m22 + m23 = 180°
m2l + m23 = 180°
Answer:
Because linear pairs of angles are supplementary. m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.
Because angles that are supplementary to the same angle are congruent. It can be concluded that ∠1 ≅ ∠3.
Step-by-step explanation:
The correct question is attached.
Linear pairs angles are angles which are formed from the intersection of two lines and they are adjacent to each other. Linear pair angles are supplementary.
If angles are supplementary to the same angle, then they are congruent.
∠1 and ∠3 are vertical angles
∠1 and ∠2 form linear pairs while ∠2 and ∠3 form linear pairs. Therefore:
m∠1 + m∠2 = 180° (linear pair angles are supplementary)
m∠2 + m∠3 = 180° (linear pair angles are supplementary)
Hence using transitive property of equality:
m∠1 + m∠2 = m∠2 + m∠3
Using subtraction property of equality by subtracting m∠2 from both sides gives:
m∠1 = m∠3
∠1 ≅ ∠3 (vertical angles are congruent)
Because linear pairs of angles are supplementary. m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.
Because angles that are supplementary to the same angle are congruent. It can be concluded that ∠1 ≅ ∠3.

Triangle A) perpendicular cross section of a cylinder
Rectangle B) shape created when a right triangle is rotated about the y-axis
Circle C) shape created when a rectangle is rotated about the y-axis
Cylinder D) parallel cross section of a sphere
Cone E) perpendicular cross section of a pyramid
Answer:
Step-by-step explanation:
Perpendicular cross section of a pyramid ------- triangle.
Imagine you cut pyramid like that. Height of pyramid would be height of your triangle. and sides of pyramid would be sides of triangle.
Perpendicular cross section of a cylinder ------- rectangle
diameter of a base of cylinder would be one side of rectangle and height of cylinder would be other side of rectangle. (pair of sides)
parallel cross section of a sphere ------ circle
when you cut sphere a side would appear with shape of circle.
shape create.... ----- cylinder.
one side of rectangle would be high of cylinder and other would be radius of it.
last one is cone. If you place right angle in coordinate beginning (0.0) and one of shorter sides to lie on y axis other would be on x axis. when rotated you get cone.

find all missing angles
Answer:
what are all the angles?
Step-by-step explanation:
Find X (the angle are X, 81, and 84)
Answer:
15
Step-by-step explanation:
the answer is 15 because a triangle has to equal 180 so all you have to do is add 81 and 84 then subtract 180 from it. like this 81+84=165 180-165=15. Hope this helps.

Using the exchange rate £1 = $1.35, calculate how many £ are in $8.70. Give your answer
rounded to 2 dp.
Answer:
£6.4
Step-by-step explanation:
£1 = $1.35
To find out the amount of £ , we would simply divide $8.70 by 1.35.
$8.70 / $1.35 = £6.4 rounded to 2 s.f.

Step-by-step explanation:
A^2+B^2=C^2
63^2+60^2=C^2
3969+3600=7569
Square root of 7569 is 87
Answer:
87
Step-by-step explanation:
Using Pythagoras' theorem in the right triangle.
The square on the hypotenuse (h) is equal to the sum of the squares on the other 2 sides, that is
h² = 60² + 63² = 3600 + 3969 = 7569 ( take the square root of both sides )
h = [tex]\sqrt{7569}[/tex] = 87

A class of 25 children is having a pizza party. Each child will eat 3/8 of a pizza. How many pizzas do they need to order?
A. 8 pizza pies at 10 pc. per pie = 80 available pieces
B. Let X be the number of children. Number of pieces eaten = 5 per child = 5X.
c. 22 pieces are left over.
D. Combine line A and line C. Total number of pieces eaten = 80 original minus 22 left over. Result 58 pieces were eaten by X children: 58 = 5X.
E. Solve the equation 58 = 5X by dividing both sides by 5.
WHOOPS! Is this a trick question? Solving the above results in the answer that there are 11.6 children at the party. Hmmm. That 0.6 child is a question mark for me.
Looks like someone miscounted the pizza slices. Or omitted some pertinent information. But, I’m sure there is a logical answer.
Answer:
10 pizzas
Step-by-step explanation:
To find the answer for this question you need to multiply 3/8 by 25.
3/8 * 25 = 9.375
You can't buy .375 of a pizza so you round it up and get 10.
Chrissie says that the equation of the line shown on the graph is y= 1/2x -5. George says that the equation of the line is y= 1/2x + 5. Which student is correct? Explain.
Answer:
wheres the graph which is provided by the question?
Step-by-step explanation:
The y-intercept of George's equation is positive. Then George's equation is correct.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Chrissie says that the equation of the line shown on the graph is y = 1/2x -5. George says that the equation of the line is y = 1/2x + 5.
From the graph, the y-intercept of George's equation is positive then George's equation is correct.

luca sells muffins and juice boxes. muffins are $1.50 each and jucie boxes are $1.25 each. write an algebraic expression for the total income luca received from the sale of muffins and juice boxes
Answer:
1.5m+1.25j
Step-by-step explanation:
m equals the number of muffins sold, and because each muffin sells for $1.50, 1.5m represents the income made from the muffins.
Same thing with the juice boxes, j equals the number of juice boxes sold, and because each juice box sells for $1.25, 1.25j represents the income made from the juice boxes.
Add the income from both of them to get the total income, and you get 1.5m+1.25j.
Ella wants to buy apples and strawberries to make a fruit tart. Apples cost 3.50 per pound and strawberries cost 3.75 per pound. How many pounds of fruit does she buy if she buys 0.5 pounds of apples and 1.5 pounds of strawberries? How many pounds of fruit does she buy if she buys x pounds of apples and y pounds of strawberries?
Answer:
2 pounds of fruit
x+y pounds of fruits
Step-by-step explanation:
The first questions asks for total amount of fruit she bought. Before that, it stated, she bought .5 pound and 1.5 pounds of apples and strawberries. The equation would be 1.5+.5= 2. The next question is asking for the total amount of fruits if X was total pounds of apples while Y was total pound of strawberry. It is again asking for the total amount so the equation would be x+y= total.
