The measure of angle B is 83, and the measure of angle C is 42. what is the measure of angle D in degrees?

a. 41

b. 45

c. 55

d. 125

C. 55 Degrees

Step-by-step explanation:

The sum of a triangle is 180 degrees. Since you already know two angles, the third one must enable the triangle to equal 180. You first add 83 and 42 together to get 125, and then subtract 125 from 180 to get 55 degrees as your answer.
