Question

Find m<2 if m<1 = 100 and m<6 = 128.

Answers and figure attached!

Answer 1

<6 +<3 =180 straight line

128+<3 =180

subtract 128 from each side

<3 = 180-128

<3 = 52

<1 + <2 + <3 = 180 sum of the angles of a triangle

100 + <2 + 52 = 180

152 +<2 = 180

subtract 152 from each side

<2 = 180-152

<2 =28
