Question

Find measure of angle C

Answer 1

angle c is also 80. alternate interior angles.

Answer 2

Answer: ∠c = 80°

Step-by-step explanation:

given that ∠a = 100°

as the angles make a line,  ∠a + ∠b = 180°

=> 100° + ∠b = 180°

=> ∠b = 180° - 100° = 80°

∴ ∠b = 80°

now ∠c = ∠b ( alternate interior angles are equal )

So ∠c = 80°
