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:



80,000,000 + 9,000,000 + 100,00 + 70,000 +300 + 20 + 6
Answer:
True, True, False
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x =−60
