Answer:
45°
Step-by-step explanation:
From the figure;
Triangle WVX is a right-angled triangle
WV= 2
WX = 1
We are required to determine, m∠X
We need to determine the appropriate trigonometric ratio to use;
Therefore, since WV is the opposite and WX is the adjacent to m∠x, then the appropriate trigonometric ratio is tangent.
That is;
Tan m∠X = WV/WX
= 2/1
tan m∠X = 1
Thus,
angle m∠X = tan⁻¹ 1
= 45°
Thus, m∠X = 45°
