Question

A and b are complementary angles and a and c are supplementary angles. If a=xº, (a) express b and c in terms of x

(b) find c - b.​

Answer 1

Explanation:

a + b = 90

a + c = 180

a) If a = x, the. we can write

x + b = 90 and x + c = 180

or

b = 90 - x

c = 180 - x

b) c - b = (180 - x) - (90 - x)

= 180 - x - 90 + x

= 90
