18. Find the measure of each numbered angle.
m∠1 = 50°, m∠2 = 90°, m∠3 = 40°, and m∠4 = 50°
m∠1 = 50°, m∠2 = 90°, m∠3 = 30°, and m∠4 = 50°
m∠1 = 70°, m∠2 = 130°, m∠3 = 20°, and m∠4 = 70°
m∠1 = 60°, m∠2 = 90°, m∠3 = 30°, and m∠4 = 60°

m∠1 = 50°, m∠2 = 90°, m∠3 = 40°, and m∠4 = 50°

Step-by-step explanation:

Angles on straight line are equal;

Vertical angles are equal,

Complementary angles add up to 90°.

Angles on straight line adds up to 180°
