Answer:

x = 60 sqrt(2)  ft

x≈84.85241374 ft

Step-by-step explanation:

7.  sin theta = opposite/ hypotenuse

sin 45 = 60/ x

Multiply each side by x

x sin 45 = 60

Divide each side by 45

x = 60 /sin 45

sin 45 = 1/sqrt(2)

x = 60 ÷ 1/ sqrt(2)

Copy dot flip

x = 60/1 * sqrt(2)/1

x = 60 sqrt(2)

x≈84.85241374
