Answer:
You are transposing so
![a = \frac{ - u}{12}](https://tex.z-dn.net/?f=a%20%3D%20%20%20%5Cfrac%7B%20-%20u%7D%7B12%7D%20)
and
![a = \frac{u}{k} + b](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7Bu%7D%7Bk%7D%20%20%2B%20%20b)
Step-by-step explanation:
Basically in transposing, you use reverse operations to get rid off attached or unnecessary terms till you get what you want on one side of the equal sign

Let the distance of the engineer from the base of the building be x, then
tan 22 = 450/x
x = 450/tan 22 = 450/0.4040 = 1,113.79
Therefore, the distance of the engineer from the base of the building to the nearest foot is 1,114 feet.
32 Round to the nearest ten is 30
Answer:
D. 157°
Step-by-step explanation:
∠EFB and ∠AFB form a linear pair, so are supplementary.
∠EFB = 180° - ∠AFB = 180° -23°
∠EFB = 157°
