Answer:
16°
Explanation:
The trig function tangent relates an acute angle of a right triangle to the measures of the adjacent and opposites sides. Those are the sides given here, so the relevant trig relation is ...
Tan = Opposite/Adjacent
tan(?) = 14/49 = 2/7
When the tangent of the angle is known, the inverse tangent function can be used to find the angle:
? = arctan(2/7) ≈ 16°
The value of "?" is about 16°.
