What are the measures of Angles a, b, and c? Show your work and explain your answers.

angle A is 40,

angle B is 50,

and angle C is 115.

Step-by-step explanation:

Angle A is 40 because it's a verticle angle, Angle B is 50 because the triangle where angle A and B are in, there is a right angle meaning it equals 180, subtract what you know from 180 (which is the 40 and the 90) which you get 50. For angle C, the circle you see for 65, it means it's a 180 angle, subtract 65 from 180 and that's angle C.
