Answer:

Step-by-step explanation:

it should add up to 360°

360=135 + 120 + 7x-64+5x-4+3x+31+4x+15+6x-8 (seems like too much huh)

360=225+25x ( much better just add the x terms and the constants together)

135 = 25x ( just subtract 225 from each side of the equation)

5.4 = x ( divide 135 by 25 )
