Given parallelogram ROCK and m R =159, find m 20.

Answer:
m∠C = 159
Explanation:
In parallelograms, opposite angles have the measure. Since angle C is opposite to angle R, we can write the following expression:
m∠C = m∠R
m∠R is equal to 159, so m∠C is equal to:
m∠C = 159
So, the answer is m∠C = 159
