A temporary support for an architectural feature is positioned 2 feet away from the wall and forms an 80* angle with the ground. How far up the wall does the support reach ?

The support reach approximately 11.34 feet up the wall.  

Step-by-step explanation:

We are given the following in the question:

The attached image shows the structure.

AC = 2 feet

We have to find AB.

We know that

Thus, the support reach approximately 11.34 feet up the wall.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
