Given;
The figure of a right angle triangle.
To find:
The value of x.
Solution:
In a right angle triangle,
[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse}[/tex]
In the given right angle triangle,
[tex]\cos (45^\circ)=\dfrac{7}{x}[/tex]
[tex]\dfrac{1}{\sqrt{2}}=\dfrac{7}{x}[/tex] [tex][\because \cos (45^\circ)=\dfrac{1}{\sqrt{2}}][/tex]
On cross multiplication, we get
[tex]1\times x=7\times \sqrt{2}[/tex]
[tex]x=7\sqrt{2}[/tex]
Therefore, the value of x is [tex]7\sqrt{2}[/tex] units.

what is the difference between multiplying fractions and adding/subtracting fractions? complete sentances pleaseo
Answer:
See explaination for answer! Hope this helps!
Step-by-step explanation:
When multiplying and deviding, you are raising them or lowering them by a certain degree, but adding or subtractions is just combining two fractions.
Just to quickly explain the "combining" aspect, during subraction, you are combining a positive with a negative.
What is the x-coordinate of the point where the lines x=4y−8 and 12x+y=11 intersect?
I like to work with the slope-intercept form of the line:
x=4y-8 �> y = (1/4)x + 2 (1)
12x+y=11 �> y = -12x + 11 (2)
At the point where they intersect the two y values must be equal, so set eq(1) = eq(2):
(1/4)x + 2 = -12x + 11
( (1/4) + (48/4))x = 9
(49/4)x = 9
Ans: x = 36/49
Check: Plug in x=36/49 to eq(1) and eq(2) to make sure they produce identical y values:
(1) y = (1/4)(36/49) + 2 = (9/49) + (98/49) = 107/49
(2) y = -12(36/49) + 11 = (-432/49) + (539/49) = 107/49 (they match)
By using substitution method,
The x-coordinate of the point where the lines x=4y−8 and 12x+y=11 intersect is [tex]\frac{36}{49}[/tex].
What is substitution method?"The substitution method is one of the algebraic methods to solve linear equations. It involves substituting the value of any one of the variables from one equation to the other equation."
We have the lines
x=4y−8 ..........................(1)
12x+y=11 .........................(2)
By using substitution method
Substitute x = 4y - 8 in equation (2)
⇒ 12(4y-8) + y = 11
⇒ 48y - 96 + y = 11
⇒ 49y = 11 + 96
⇒ y = [tex]\frac{107}{49}[/tex]
Calculating the x - coordinate by substituting y value in equation (1)
x=4y−8
⇒ x = [tex]4(\frac{107}{49} )-8[/tex]
⇒ x = [tex]\frac{428-392}{49}[/tex]
⇒ x = [tex]\frac{36}{49}[/tex]
Hence, the x-coordinate of the point where the lines x=4y−8 and 12x+y=11 intersect is [tex]\frac{36}{49}[/tex].

HELPPPPOMOGMGOGMGOGKM PLS ANSWER THIS CORRECTLY PLZZZ THIS IS FOR A VERY IMPORTANT TEST YOUWILL GET BRAINLIEST HELP
Answer:
i cant give u the answer but here is an example hope this helps slope = "rise over run" the difference in y values divided by the difference in x values
= 6/-3 = -2 = m. It's negative because as x increases, y decreases
plug that into the point slope formula, with either point. generally use the most simple point
y-h= m(x-k) where m= -2 and (k,h) = (2,-2)
y+2 = -2(x-2)
simply if you want
Y = -2x +4 -2 = -2x +2
or
2x +y = 2
Step-by-step explanation:
Answer:
Your slope is -1
Your y inter is -3

Given a point translated from A(1,2) to B(4,4). If a point C at (0,0) is translated in the same way, what will be its new endpoints?
A.(−3,−2)
B.(3,2)
C.(2,2)
D.(3,3)
please help
Answer:
B. (3,2)
Step-by-step explanation:
Step 1) When shifting from A(1,2) to B(4,4), the point shifted 3 units to the right (which means x=3) and 2 units upwards (which means y=2).
Step 2) So when you apply the same movements to point C(0,0), the new point will be (3,2).
See the diagram below. Step 1 is the graph on the left. Step 2 is the graph on the right. The movement is colored in green. Hope this helps!
Explain how to write and evaluate the algebraic expression 13 less than the quotient of forty and a number; evaluate when n=2
Answer:So you would start with 40/n because quotient means division and then it would be (40/n) - 13 (40 divided by n then minus 13) because the answer is thirteen less than the quotient of those numbers. since it wants you to evaluate for n=2 you would do 40/2 which is 20 then subtract 13 which is 7.
So write the expression as (40/n) -13 and when you evaluate just stick the 2 where the n is for (40/2) - 13
20 - 13
= 7
Step-by-step explanation: HOPE THAT THIS WILL HELP YOU ❤️
Answer:
Here's an answer I used <3
Explanation:
You would then get to 40/n because quotient means division, then 40/n-13 because the outcome is 13 below the quotient. You can divide 40 by 20 to get 20, then 13 to get 7 because it asks you to test n=2.
what is the scale factor of triangle abc and triangle def
Answer:
The answer is 6
Step-by-step explanation:
ABC is 72, 66, 42 and DEF is 12, 11, 7
simply divide the largest shape measurements by the smaller one.
72÷12
66÷11
42÷7
you get 6 in all of them, this technique may not work all the time.
