Question

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

Answer 1

m∠C = 159

Step-by-step 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
