Hello there!

On those type of angles, the angles that are facing each other is equal to another.
So you can set up the equation like this : 

10x + 1 = 12x - 5
        -2x = -6
          x = 3

So the answer is x = 3.



In some problems, you have to find the angle.
Then you just simply substitute 3 into x.

10x + 1
10(3) + 1
30 + 1
31

12x - 5
12(3) - 5
36 - 5
31
The angles are 31° and 31°.

Hope this helped! :)

QF Q6.) Find the function for b.
Dimas [21]
The function notation f(x)=2x-4 means replace the x on the right-hand side with the value in parentheses on the left.
For example, f(y)=2y-4; f(4)=2(4)-4=4; f(1)=2(1)-4=-2 and so on.
The same principle applies to g(x), for example
g(2)=4(2^2)-3=13,
g(x+1)=4(x+1)^2-3=4(x^2+2x+1)-3=4x^2+8x+4-3=4x^2+8x+1
and so on.

(g of f)(x) is another way to write g(f(x)), therefore
g(f(x))
=g(2x-4)   [because f(x)=2x-4
=4(2x-4)^2-3
=4(4x^2-16x+16)-3
=16x^2-64x+64-3
=16x^2-64x+61

FinnZ [79.3K]
2x+2x+60=180 because the angles have to add up to 180

So you have

4x+60=180

4x=120

x=30
