Question

What is the supplementary angle to 69 degrees

Answer 1

Supplementary angles add up to 180 degrees so by doing 180-69 we know that the supplementary angle is 111 degrees

Answer 2

let , the supplementary angle be x

then,

x + 69 = 180

x = 180 - 69

x= 111 degrees

so the supplementary angle of 69 degrees is 111 degrees
