KJI = KJY + YJI

Thus ;

`168 =( 8x - 4) + (36x - 4)`

`168 = 8x - 4 + 36x - 4`

Collect like terms

`168 = 44x - 8`

Add sides 8

`168 + 8 = 44x - 8 + 8`

`176 = 44x`

Divide sides by 44

`(176)/(44) = (44)/(44) x \\`

`(16 * 11)/(4 * 11) = x \\`

`4 = x`

`x = 4`

So ;

`YJI = 36x - 4`

`YJI = 36(4) - 4`

`YJI = 144 - 4`

`YJI = 140°`
