Question

Help with this problem please

Answer 1

B. m<1 = 35 m<2 = 30

Explanation:

use the angle 115 as a starting point

a straight line = 180 degrees and there is a measured 115 degrees already

180 - 115 = 65

each triangle is made up of 180 degrees

in the first triangle, you are given 80 degrees, and you just solved for another angle which is 65 degrees

180 - 80 - 65 = 35

m<1 = 35

in the second triangle, you are given 85 degrees, and you already solved for the other angle which is 65 degrees

180 - 85 - 65 = 30

m<2 = 30

Answer 2

<1 = 35

<2 = 30

Explanation:

The exterior angle is equal to the sum of the opposite interior angles

<1 + 80 = 115

<1 = 115-80

<1 =35

<2 +85 = 115

<2 = 115-85

<2 = 30
