Embankment 7879

An embankment 7.5 m high should be built on the horizontal plane. The width of the upper surface of the embankment is 2.9 m, and the slope is 35 °. What will be the lower width of the embankment?

Correct answer:

x =  13.4031 m

Step-by-step explanation:

a=2.9 m h=7.5 m  tan 35°  = y/h  y=h tan35°=tan7π/36=5.25156 m  x=a+2 y=2.9+2 5.2516=13.4031 m
