Answer:
m∠b = 92 ; m∠c = 92
Step-by-step explanation:
∠b and ∠c both form supplementary angles with the 88° angle. I'll just choose b in this instance.
b + 88 = 180
b = 92
Now we know that ∠b is 92°.
Moreover, ∠c and ∠b are known as vertical angles meaning they are equivalent to each other. Therefore, ∠c is also 92°
