Answer:
35°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationship between trig functions and sides of a right triangle. The pole and its shadow form the legs of the right triangle with the side adjacent to the angle of elevation being the shadow. "TOA" tells you ...
Tan = Opposite/Adjacent
tan(elevation angle) = (pole height)/(shadow length)
tan(elevation angle) = 35/50 = 0.7
The inverse tangent function, arctan( ) or tan⁻¹( ), is used to find the angle from the value of its tangent.
elevation angle = arctan(0.7) ≈ 34.99° ≈ 35°
