Answer: See explanation
Step-by-step explanation:
m∠A and m∠O are alternate interior angles so they're congruent.
m∠A = m∠O
m∠A = 65°
AM and SO are congruent sides
AM = SO
AM = 86
m∠S and m∠M are alternate interior angles so they're congruent.
m∠S = m∠M
m∠S = 60°
ON and NA are congruent sides.
ON = NA
ON = 75
m∡SNO, m∠S, and m∠O form a triangle so they should add up to 180°
m∡SNO + m∠S + m∠O = 180°
m∡SNO + 60 + 65 = 180
m∡SNO + 125 = 180
Subtract both sides by 125
m∡SNO = 55°
