I’m doing homework and i don’t know how to find x

x=15

Step-by-step explanation:

(x+10)=(4x-35)               Set them equal to each other

x+10=4x-35

-x +35| -x+35                subtract x from both sides and add 35 to both sides

45=3x

                           divide by 3, which will give you the answer

3     3

15=x

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

answer: c.  

step-by-step explanation:
