I have attached an image of the right trapezoid.
Answer:
C: 107°
Step-by-step explanation:
From the image attached, we can see that the right trapezoid has 2 internal angles which are right angles while it has a third angle which is 73°.
Now,we want to find angle WXY.
Sum of angles in a trapezoid is 360°.
Thus;
90 + 90 + 73 + ∠WXY = 360
253 + ∠WXY = 360
∠WXY = 360 - 253
∠WXY = 107°
Answer:
C. 107°
Step-by-step explanation:
In a trapezoid, adjacent angles are supplementary, meaning they add up to 180°.
∠W and ∠WXY are adjacent, so they are supplementary. 180° - 73° = 107°.
Another way to do this is to know that there are 360° in a trapezoid. This is a right trapezoid, so two of the angles are 90°. One angle is 73°. 90° + 90° + 73° = 253°.
360° - 253° = 107°.
