Final Answer:

In a right-angled triangle, the tangent of an angle is defined as the ratio of the length of the opposite side to the length of the adjacent side.C. WY = 101, mZ = 132°.

Step-by-step explanation:

To find the length of WY and the measure of angle Z, we can use trigonometric relationships in a right-angled triangle. Let's denote the length of side WY as 'a' and the measure of angle Z as 'b'. According to the given options:

Option A: WY = 72, mZ = 132°

Option B: WY = 101, mZ = 72°

Option C: WY = 101, mZ = 132°

Option D: WY = 132, mZ = 101°

We need to find the option that satisfies the trigonometric relationship in a right-angled triangle. The most common trigonometric relationship in this case is the tangent of an angle, which is the ratio of the opposite side to the adjacent side.

tan(b) = Opposite/Adjacent

In a right-angled triangle with angle Z, tan(b) = WY / ZX.

Now, let's evaluate each option:

Option A: tan(132°) = 72 / ZX

Option B: tan(72°) = 101 / ZX

Option C: tan(132°) = 101 / ZX

Option D: tan(101°) = 132 / ZX

Comparing the ratios, we find that option C is the correct solution as it satisfies the given trigonometric relationship. Therefore, WY = 101 and mZ = 132°.
