Answer:


b = 90


c=80


d =100

Explanation:

Given

See attachment

Required

Find b, c and d

First, we solve for b using:


b + 10 + b - 10 = 180 --- base angles of a parallelogram

Collect like terms


b + b =180+10-10


2b = 180

Solve for b


b = 180/2


b = 90

Then, we have:


d =b + 10


c = b - 10 --- opposite angles

So, we have:


d =90 + 10


d =100


c = 90 - 10


c=80
