Answer:
m< WXZ = 73
m< ZXY = 87
Step-by-step explanation:
WXY = WXZ + ZXY
WXY = 5x+8+7x-4
WXY = 12x+4
m < WXY = 160
160 = 12x + 4
156 = 12x
13 = x
WXZ = 5x + 8
= 5*13 + 8
= 73
ZXY = 7x - 4
= 7*13 - 4
= 87
[tex]\\ \sf\Rrightarrow 5x+8+7x-4=160[/tex]
[tex]\\ \sf\Rrightarrow 12x+4=160[/tex]
[tex]\\ \sf\Rrightarrow 12x=156[/tex]
[tex]\\ \sf\Rrightarrow x=13[/tex]
