32-3 which is 29 Im pretty sure
Answer:
the answer should be 7a^3-4a^2-2a-87
Answer:
Step-by-step explanation:
I would solve this using tangents. Let h be height of flagpole.
Set up 2 right triangles, each with a base of 40.
The larger triangle has height of "h+70"
Smaller triangle has height of 70.
Now write the tangent ratios:

Note: A-B = 9
To solve for h we need to use the "Difference Angle" formula for Tangent

Plug in what we know:
