Let's see what to do buddy...

Step (1)
We know that the sum of the interior angles of any n-sided figure is obtained from the following equation :
Our figure has 5 sides ;
So , sume the interior angles of it equals :

Step (2)
First look at the photo which I post.
According it we have :
Subtract the sides of the equation minus 465 :

And we're done.
Thanks for watching buddy good luck.

Answer:
76 degrees
Step-by-step explanation:
GE = 180 since it is a straight line
GE = GR + FE
180 = 7x+6 +6x-8
Combine like terms
180 = 13x-2
Add 2 to each side
182 = 13x
Divide by 13
182/13 = 13x/13
14 =x
We want FE
FE = 6x-8
FE = 6(14) -8
=84 -8
=76
What you want to do is cross multiply so you get 5(x+4)=7(3x+28) then you distrubute the 5 and then you distribute the 5 and the 7 to the number in the parentheses 5x+20=21x+196
subtract 5x on both sides to get 20=16x+196 then you subtract 196 on both sides to get -176=16x last what you want to do is divide 16 on both sides to get x=-11
