Question

∠3 and ∠6 are alternate interior angles. If m∠3 = 75, what is the measure of ∠6

a. 15°
b. 75°
c. 105°
d. 180°​

Answer 1

B. m<3 = m<6 = 75degrees

Explanation:

First you must understand that in geometry, the alternate interior angles are equal

Hence if ∠3 and ∠6 are alternate interior angles, then <3 = <6

Given that m<3 = 75 degrees

m<6 will also be 75 degrees since both angles are equal
