Answer:
set both of them equal to each other:
8x - 8° = 5x + 25°
subtract 5x by both sides of the equations and it becomes:
3x-8° = 25°
now add 8° both sides:
3x = 33°
divide three by both sides:
x = 11°
now thats done to find B:
plug your x value in the B equation:
5x + 25°
5(11) +25°
55 +25°
not sure if you can add here sorry :(. I hope this helped so far :)

Make your fractions have common denominators
</span>13-((32/40)+(30/40))
Add your fractions and simplify
13-(62/40)
or
13-(31/20)
or
13-(1 11/20)
Then turn 13 into a fraction with a common denominator! Im going to use the second fraction method (31/20)
13 written as a fraction is 13/1, its LCD with 31/20 is 20. I now multiply the top and bottom by 20
260/20
Now I rewrite the problem again
(260/20)-(31/20)
Which equals
229/20!
This is your unsimplified answer
Finally you simplify and get
11 9/20
