Answer:
43°
Explanation:
You want the measure of an angle in a right triangle that has opposite side 16 and adjacent side 17.
Tangent
The tangent relation is ...
Tan = Opposite/Adjacent
In this figure, that means ...
tan(?) = 16/17
Arctangent
The value of the angle is found using the inverse tangent function. (The calculator mus be in degrees mode.)
? = arctan(16/17)
? ≈ 43°
