The ditch profile is an isosceles trapezoid with bases of length 80m and 60m. The slope of the sidewall of the ditch is 80°. Calculate the ditch depth.

Correct answer:

h =  56.7128 m

Step-by-step explanation:

a=80 m c=60 m x=(ac)/2=(8060)/2=10 m tan 80° = h/x  h=x tan80°=tan4π/9=56.713=56.7128 m
