Answer:

x = -4

y = 14

m< 1 = 66 degrees

m< 2 = 24 degrees

m< 3 = 156 degrees

Explanation:

<1 + <2 = 90 degrees

3y -6x + 5y - 46 = 90 degrees

8y - 6x = 136 degrees


<2 + <3 = 180 degrees

5y - 46 + 12y + 3y = 180 degrees

17y + 3x = 226

A system of equations. Substitution or addition.

(8y -6x = 136) + 2(17y + 3x = 226)

(8y-6x = 136) + 34y + 6x = 452) =

42y = 588

y = 588/42

y = 14

8(14)-6x=136

-6x = 136 - 112

X = - 4

m <1 = 3(14)-6(-4)=66 degrees.

m <2 = 5(14)-46

m <2 = 24 degrees

m <3 = 12(14) + 3(-4)

m <3 = 156 degrees
