There are 13 spades in a deck, so the probability is 1/4. There are 4 King’s in the deck, but a king can also be a spade, so what would be 1/13 is actually 3/52. So add the probabilities together, and you get 13/52 + 3/52 = 16/52, or 4/13

In parallelogram WXYZ, with diagonal XZ, m∠WXZ = 81° and m∠WZX = 28°. What is the measure of ∠XYZ?
Lisa [10]

The measure of angle XYZ in the parallelogram is: 71°.

<h3>What are the Opposite Angles of a Parallelogram?</h3>

In a parallelogram, the angles that are opposite each other are congruent.

Find m∠XWZ using the triangle sum theorem:

m∠XWZ = 180 - m∠WXZ - m∠WZX

m∠XWZ = 180 - 81 - 28

m∠XWZ = 71°

m∠XWZ = m∠XYZ [opposite angles are congruent]

m∠XYZ = 71°
