Answer:
The error are
1) The use of the angle addition postulate, for [tex]m \widehat{ACD}[/tex]
2) The assumption that [tex]m \widehat{BC}[/tex] = 90°
The vertical angle property between [tex]m \widehat{CD}[/tex] and [tex]m \widehat{FA}[/tex] should be used to find 'x'
x = 5
Step-by-step explanation:
From the drawing of the circle, we are given;
AD = A diameter of the circle
∴ [tex]m \widehat{ACD}[/tex] = 180°
By angle addition postulate, we have;
[tex]m \widehat{ACD}[/tex] = [tex]m \widehat{AB}[/tex] + [tex]m \widehat{BC}[/tex] + [tex]m \widehat{CD}[/tex]
By substitution property of equality, we have;
180° = [tex]m \widehat{AB}[/tex] + [tex]m \widehat{BC}[/tex] + [tex]m \widehat{CD}[/tex]
[tex]m \widehat{AB}[/tex] = 5·x°
[tex]m \widehat{BC}[/tex] = Not given
[tex]m \widehat{CD}[/tex] = 15·x°
However;
[tex]m \widehat{CD}[/tex] is the vertically opposite angle to [tex]m \widehat{FA}[/tex]
∴ [tex]m \widehat{CD}[/tex] = [tex]m \widehat{FA}[/tex] = (16·x - 5)°
[tex]m \widehat{CD}[/tex] = 15·x° = (16·x - 5)°
15·x° = (16·x - 5)°
∴ 5 = 16·x° - 15·x° = x
x = 5
[tex]m \widehat{BC}[/tex] = 180° - ([tex]m \widehat{AB}[/tex] + [tex]m \widehat{CD}[/tex]) = 180° - (15·x° + 5·x°) = 180° - (20·x°)
[tex]m \widehat{BC}[/tex] = 180 - (20×5)° = 80°
[tex]m \widehat{BC}[/tex] = 80°
The error are the use of the angle addition postulate, for [tex]m \widehat{ACD}[/tex], and the assumption that [tex]m \widehat{BC}[/tex] = 90° rather than the vertical angle property between [tex]m \widehat{CD}[/tex] and [tex]m \widehat{FA}[/tex] in trying to find 'x', from which x = 5.

How to solve this triangle, please help me.
Answer:
sum of angles in a triangle is 180
so 70+60+ 8x+2 = 180
132+ 8x = 180
8x = 180-132
x = 48/8
x= 6
then find the angle by substituting value of x
8x + 2
8*6 + 2
= 50°
Which equation describes the table shown:

A group of friends were working on a student film. They spent all their budget on equipment and costumes. They spent $737 on equipment, and 33% of the total budget on costumes. What was the total budget for their student film?
Answer:
Budget= $1,100
Step-by-step explanation:
Giving the following information:
They spent $737 on equipment and 33% of the total budget on costumes.
If they spent all their budget on equipment and costumes, then the percentage spent on equipment was 67% (100 - 33).
Then, to calculate the total budget, we need to use the following formula:
Budget= 737 / 0.67
Budget= $1,100
Cheryl painted her living room walls with two different colors. She painted part of the room yellow and another part green. If the surface area of the walls in her room is 720 ft2 and she painted 288 ft2 yellow, what percent of the room did she paint green?
Answer:
Total percent of the room did she paint green = 60%
Step-by-step explanation:
Given - Cheryl painted her living room walls with two different colors. She painted part of the room yellow and another part green. If the surface area of the walls in her room is 720 ft² and she painted 288 ft² yellow.
To find - What percent of the room did she paint green ?
Proof -
Given that,
The surface area of the walls in her room = 720 ft²
Total area painted in yellow color = 288 ft²
So,
Total area painted in green color would be = 720 - 288 = 432 ft²
Now,
Let the total percent green color painted = x
So,
720 × x% = 432
⇒[tex]720*\frac{x}{100} = 432[/tex]
⇒ x = [tex]\frac{432*100}{720}[/tex] = 60
∴ we get
Total percent of the room did she paint green = 60%
4 divided by 1/2 show your work
Answer:
8
Step-by-step explanation: frst 1/2=0.5
4/0.5=8
Answer:
4 divided by 1/2 is equal to 8
Step-by-step explanation:
basically do 4*2 and you will get your answer
or you should know that 1/2=0.5
so how many 0.5 are in 4, 2 0.5's are in 1 so you have to do 2*4

Answer:
x = 3
y = 8
Step-by-step explanation:
ok we will substitute
y = x + 5
into the second equation
4x + y = 20
4x + (x + 5) = 20
5x + 5 = 20
5x = 15
x = 3
y = x + 5 = 3 + 5 = 8
Answer:
4(3)+y=20
Step-by-step explanation:
4*3=12
Y= 3+5
3+5=8
12+8=20

Solve please. 20 points.
Answer:
336 cm^2
Step-by-step explanation:
Well theres not exactly a formula, I jsut solve the 3 faces and then double it all since 2 are the same for each except for 1 so the first side is the 10X12 one. that would give you 60 and then you double that and get 120 since 2 same faces.
The next one the 6X13 one is just a sideways rectangle, a=lw and that would be 78. Two faces same side double 78 and get 156.
Now the final side is the bottom which is jsut 10X6. a=lw and that would eqaul 60. No need to double since thats the only side that doesn’t have a duplicate. Add all your result up and you would get
336 cm^2

A chef used 6 cups of flour for every 2 cups of sugar to bake a cake. If he uses 12 cups of sugar, how many cups of flour did he use?
Answer:
36
Step-by-step explanation:
2 goes into 12 6 times and 6x6 = 36.
mallory and five of her friends bought a box of 36 cookies. together they ate 2/3 of the cookies
Answer:
24 cookies got eaten 12 weren't eaten
Step-by-step explanation:
36 divided by 3 = 12
12 x 2 = 24 ( since they ate 2/3)
36-24=12 (12 weren't eaten)
16 gallons of water are used to completely fill 5 fish tanks. If each tank holds the same amount of water, how many gallons will each tank hold?
I have to find the missing angles
Answer:
Angle 3 = 115°
Angle 4 = 22°
Angle 5 = 43°
Angle 6 = 115°
Step-by-step explanation:
These two triangles are congruent by SSS. It is given that two sides are congruent already, and by the reflexive property, they share a side and therefore have a third congruent side.
By CPCTC, all of their angles and sides are also congruent. And by the triangles angle sum theorem, side 3 and 6 must equal 115°
~~~
Have a nice day. Feel Free to ask questions. Spread the love.
Step-by-step explanation:
4 = 22⁰
5 = 43⁰
3 and 6 are same
kite total angles = 360⁰
so, to find 3 and 6, we need to subtract all angles we have and devide it with 2 because we need to find 2 angles...
360-22-22-43-43= 230
3 and 6 = 230 ÷ 2
= 115⁰
