Answer:
x = 22
Step-by-step explanation:
Add the expressions for the angle measures.
5x + (3x + 4) + (3x + 4) + 5x = 360
Combine like terms.
16x + 8 = 360
Subtract 8.
16x = 352
Divide by 16.
x = 22

13x+25=0
13x+25-25=0-25 Since two opposites added give zero, remove them from the expression 13x=-25
its all about the angles just subtract the number you have from the total
