Question

Let measure of angle a =40 degrees , if angle b is complement of angle a and c is supplement of angle B , what is measure of b + measure of c

Answer 1

Answer: b= 50

c=130

Explanation:

Answer 2

Complementary angles ( a and b ) are equal to 90 °
90° - a = b
90° - 40° = b
b = 50°
Supplementary angles ( b and c ) are equal to 180 °, so..
180° - b = c
180° - 50° = c
c = 130°
Measure b + Measure c = 180° btw
