Answer:

x=26

Step-by-step explanation:

exterior angles theorem meaning they're equal to each other.

5x+7=8x-71

add 71 to 7

5x+78=8x

subtract 5x from 8x

78=3x

divide 78 and 3

x=26

to check your work plug 26 into each equation:

5(26)+7= 137°

8(26)-71= 137°

because they're the same you know that x must equal 26

hope this helps!❤
