Answer:
42 degrees
Explanation:
first you have to put the two equations given equal to each other because since ET bisects it the two sides are equal to each other
5x+7 = 8x-14
then you solve for x
- first get rid of 5x
7=3x-14
- second you move the 14 over
21 = 3x
- last divide 3 into 21
21/3= 7
x=7
then plug 7 into the one or both of the equations
5(7)+7= 35+7= 42
8(7) - 14= 56 - 14= 42
42 degrees is the answer
