Answer:

42 degrees

Step-by-step 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
