Answer: See explanation

Explanation:

10) Same side interior angles add up to 180°

3x + x = 180

4x = 180

x = 45

11) Same side interior angles add up to 180°

5x + 3x = 180

8x = 180

x = 22.5

12) 6x is vertical to an angle that has a relationship with 3x (same side interior angles) which means 6x and 3x have to add up to 180° as well

6x + 3x = 180

9x = 180

x = 20

Answer:

10)

180-3x =x (corresponding angles are equal)

x=45°

11)180-5x=3x ( same reason)

x=10°

12)180-6x=3x(same reason)

x=20°
