Answer:
the angle Ф is 63.9 degrees.
Step-by-step explanation:
A right triangle describes this situation. The height of the triangle is 45 ft and the base is 22 ft. The ratio height / base is the tangent of the angle of elevation and is tan Ф. We want to find the angle Ф:
opp
tan Ф = ---------- = 45 / 22 = 2.045.
adj
Using the inverse tangent function on a calculator, we find that the angle Ф is 63.9 degrees.
