I need help fast. Please. You need to use Pythagorean theorem

Answer:
51 ft
Step-by-step explanation:
The 2 right triangles in the diagram are similar thus the ratios of corresponding sides are equal.
let h be the height of the pole, then
[tex]\frac{h}{6}[/tex] = [tex]\frac{85}{10}[/tex] ( cross- multiply )
10h = 510 ( divide both sides by 10 )
h = 51
The height of the flag pole is 51 ft
