Question

If m < WXY = 160 what are the m< WXZ and m < ZXY

Answer 1

`\\ \sf\Rrightarrow 5x+8+7x-4=160`

`\\ \sf\Rrightarrow 12x+4=160`

`\\ \sf\Rrightarrow 12x=156`

`\\ \sf\Rrightarrow x=13`

• <WXY=5(13)+8=65+8=73
• <ZXY=7(13)-4=91-4=87

Answer 2

m< WXZ = 73

m< ZXY = 87

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
