Question

9) If 22 - 42 and 21 and 22 and complementary angles, find mzi
2. What's the measure of an angle that is 19 times the measure of a supplementary
angle?
3. Two complementary angles are in the ratio 2:1. What is the measure of

Answer 1

Step-by-step explanation:

2. complementary means sum is 90....

consider one angle as x. then other pair is 19 times x. ie, 19x.

sum of the pairs is 90°

x + 19x = 90

20x = 90

x=9÷2.

x=4.5

3. sum of the angle is 90°.

let one be x.

therefore angles are in the Ratio 2:1

let it be 2x : 1x

sum is 90

3x=90

x=30°.

do your problem.

thank me later
