Vikentia [17]

Answer:

1: 130

2: 70

Step-by-step explanation:

Supplementary angles add up to equal 180

So to find the measure of the missing angles, we subtract the measure of the known angles from 180

For #1

∠B = 180 - 50

180 - 50 = 130

Hence ∠B = 130

For#2

∠D = 180 - 110

180 - 110 = 70  

Hence, ∠D = 70
