Question

(a) An angle measures 61°. What is the measure of its supplement?

(b) An angle measures 39'. What is the measure of its complement?

Answer 1

(a)119°

(b)51°

Explanation:

(a)Subtract the given angle from 180.

=180°-61°

=119° (The supplement of 61° is 119°)

(b)Subtract the given angle from 90.

=90°-39°

=51° (The complement of 39° is 51°)

Answer 2

61+x=180

x=180-61

x=119

y+39=90

y=90-39

y=51
