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°
