Answers for m1 m2 m3

Answer 1

<1 = 30

<2= 41

<3 = 96

Explanation:

Angle 1 ,66 and 84 form a triangle and triangles add to 180 degrees

<1 + 66 + 84 = 180

Combine like terms

<1 +150 = 180

Subtract 150 from each side

<1 + 150 -150 = 180-150

<1 = 30

Angle 3 and 84 form a straight line. A straight line is 180 degrees.

<3 + 84 =180

Subtract 84 from each side

<3 +84-84 = 180 - 84

<3 = 96

<2 , <3 and 43 form a triangle which adds to 180 degrees,

<2 + <3 + 43 = 180

We have already found <3 to equal 96 degrees

<2 + 96+43 = 180

Combine like terms

<2 +139=180

Subtract 139 from each side.

<2 +130-139 = 180-139

<2 = 41
