Answer:
[tex]m\angle B = 50^\circ[/tex]
[tex]m\angle C = 130^\circ[/tex]
Step-by-step explanation:
We are given the following information in the question:
[tex]m\angle A = 40^\circ[/tex]
Angle B is a complement of Angle A. Thus, we can write:
[tex]\angle A + \angle B = 90^\circ\\\angle B = 90 - m\angle A\\\angle B = 90 - 40 = 50\\m\angle B = 50^\circ[/tex]
Angle C is a supplement of Angle B. Thus, we can write:
[tex]\angle C + \angle B = 180^\circ\\\angle C = 180 - m\angle B\\\angle C = 180 - 50 = 130\\m\angle C = 130^\circ[/tex]
Answer:
the answer is m angle B = 50
m angle C = 130
