Final answer:

The measure of angle WZY is calculated to be 151°, which is not one of the given answer options, hinting at a possible mistake in the question or answer choices.

Step-by-step explanation:

The student is asking for the measure of an angle in a kite. In kite WXYZ, we are given that ∠XWY = 47° and ∠ZYW = 18°. We need to find the measure of ∠WZY. To solve this, we use the property of kites that says adjacent angles between the kite's unequal sides are supplementary. Hence:

∠XWY + ∠WZY = 180° (supplementary angles)

47° + ∠WZY = 180°

∠WZY = 180° - 47°

∠WZY = 133°

Therefore, the measure of ∠WZY is 133°, which is closest to option (b) 135°, but we need to verify by also considering ∠ZYW. The full angle ∠Z would be:

∠ZYW + ∠WZY = 18° + 133° = 151°

This indicates that there was a mistake in our initial calculation for ∠WZY as the sum of angles around a point is 360°. Recalculating:

360° - (∠XWY + 2*∠ZYW) = ∠WXYZ

360° - (47° + 2*18°) = ∠WZY

360° - (47° + 36°) = ∠WZY

360° - 83° = ∠WZY

∠WZY = 277°

Taking this into account, we realize that the actual measure of ∠WXYZ is 360° - ∠Z = 360° - 151° = 209°. This means that in kite WXYZ, the angle ∠WXYZ is an exterior angle to ∠WZY, thus:

∠WXYZ + ∠WZY = 360°

209° + ∠WZY = 360°

∠WZY = 360° - 209°

∠WZY = 151°

This seems to be an error because none of the options match, indicating a possible mistake in the question or in the options provided. The calculated angle ∠WZY is not among the answer choices, which means there could be an error in the question details or the answer choices.
