What is the value of x?<br> Enter your answer, as a decimal, in the box.<br> ft

Lilit [14]

Answer:

67.5 ft.

Step-by-step explanation:

Length of MA = 71.5 - 22 = 49.5 ft.

Length of BP = 97.5 - x.

So we have the equation:

22 / 49.5 = (97.5- x) / x

Cross multiply:

22x = 49.5(97.5 - x)

22x = 4826.25 - 49.5x

22x + 49.5x = 4826.25

71.5x = 4826.25

x = 4826.25/71.5

x= 67.5 ft.
