Question

9. Lines A and B are parallel lines. Find the measures of angles 1, 2 and 3. ​

Answer 1

<1 = 33

<2 = 90

<3 = 57

Explanation:

<3 = 57 because of alternate interior angles

<2 + <3 + 33 = 180

<2 + 57 + 33 = 180

<2 + 90 = 180

<2 = 90

<1 + <2 + 57 = 180

<1 + 90 + 57 = 180

<1 + 147 = 180

<1 = 33
