Answer:
The answer is -3 + 7y +2x
Step-by-step explanation:
The two base angles of an isoceles triangle are equal so we can conclude that
2x - 20 = x + 8
Now we just need to solve for x:
2x - 20 + 20 = x + 8 + 20
2x = x + 28
2x - x = x + 28 - x
x = 28
So, angle B = x + 8 which is 28 + 8 = 36°
DG and EF are the same length, they are sides of a parallelogram

Step-by-step explanation:
Answer:
x = - 50
Step-by-step explanation:
-2/5 x - 2 = 18
-2x - 10 = 90
-2x = 100
x = - 50
