Question

How tall is the flagpole? X 6 ft 15 ft 4.5 ft

Answer 1

Answer:

x = 20 ft

Step-by-step explanation:

We can use similar triangles and ratios to solve

4.5 ft         6 ft

--------- = ---------------

15 ft             x ft

Using cross products

4.5x = 15*6

4.5x =90

Divide each side by 4.5

4.5x/4.5 = 90/4.5

x =20
