Answer:

see below

Explanation:

The sum of the interior angles is 180

<1 + <2 + <4 = 180

<1 + 31+ <4 = 180

<1 + <4 = 180-31

<1 + <4 = 149

<2 + <3 = 180 because it forms a straight line

31 + <3 = 180

<3 = 180-31

<3 = 149

Setting theses equal (since they are both equal to 149)

<1 + <4 = <3

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