Answer:
Angle E = 70°
Step-by-step explanation:
Given parallelogram RELA, where m<R = 110°, to find m<E, recall the properties of a parallelogram.
Angle R and angle E are consecutive angles in parallelogram RELA.
One of the properties of a parallelogram states that any 2 consecutive angles in a parallelogram are supplementary. That is, they add up to 180°.
Therefore:
m<R + m<E = 180°
110° + m<E = 180°
Subtract 110° from both sides
m<E = 180° - 110° = 70°
