Answer:
87, 73 (solution A)
Step-by-step explanation:
We know that angle WXY is 160 degrees. Therefore, (5x+8)+(7x-4)=160.
(5x+8)+(7x-4)=160
5x+8+7x-4=160
12x=156
x=13
Now that we have x, we can plug them in to the expressions to find the measures of the given angles.
7(13)-4=87 degrees (angle WXZ)
5(13)+8=73 degrees (angle YXZ)
