Answer:
x° ≈ 50.0°
Step-by-step explanation:
The sides adjacent and opposite the angle are given. The appropriate trig relation is ...
Tan = Opposite/Adjacent
tan(x°) = 50/42
The inverse function is used to find the angle whose tangent is a particular value:
x° = arctan(50/42) ≈ 49.9697°
x° ≈ 50.0°
