Question

A point near the top of a ramp is about

77

ft from a point at the base of the ramp​ (measured along the incline of the​ ramp). This top point is also directly abouve a point of the ground 60 ft from the same base point. What angle does the ramp make with the​ ground?

Answer 1

Right triangle.

Hypotenuse=77

horizontal (bottom side)=60

cos(angle)=adjacent/hypotenuse

cos(angle)=60/77

angle= cos^-1(60/77)
