Answer:
angle ZXY= 5x+8 = 5(13)+8 =73
angle ZXW= 7x-4= 7(13)-4=91-4=87 degrees
it is a
Step-by-step explanation:
add two angles together = 160
5x+8+7x-4=160
12x+4=160
12 x =160-4
x=156/12= 13
angle ZXY= 5x+8 = 5(13)+8 =73
angle ZXW= 7x-4= 7(13)-4=91-4=87 degrees

They are called vertical angles because the definition of vertical is: <span>in a direction, or having an alignment, such that the top is directly above the bottom. The "angles opposite each other when two lines cross" match the definition.</span>
