Answer:
PQ = 20
Step-by-step explanation:
Theorem: The length of the median of a trapezoid is the average of the base lengths.
![\frac{PQ + 12}{2} = 16](https://tex.z-dn.net/?f=%5Cfrac%7BPQ%20%2B%2012%7D%7B2%7D%20%20%3D%2016)
PQ + 12 = 32
PQ = 20
See how easy that is if you know the theorem!
Answer:
∠a = 39°
∠b = 129°
Step-by-step explanation:
Vertical angles are congruent. An exterior angle of a triangle is equal to the sum of the remote interior angles.
<h3>Application</h3>
Angle y and angle 'a' are vertical angles, so congruent.
∠a = ∠y = 39°
The angle marked 'b' is an exterior angle to the triangle. Its remote interior angles are 'a' and the one marked 90°.
∠b = ∠a +90° = 39° +90°
∠b = 129°
