Question

two complmentry angles are in ratio 2:1 find its measure​

Answer 1

Answer:

30° and 60°

Step-by-step explanation:

Angle 1 = 2x

(As the measure of the angle is not 2 degrees but infact 2 multiplied by a common factor)

Angle 2 = 1x

(As the measure of the angle is not 1 degrees but infact 1 multiplied by a common factor)

                       ====================================

The angles are complimentary, thus

2x + 1x = 90

=> 3x = 90

=> x = 90/3

=> x = 30

                       ====================================

2x = 60

1x = 30

Answer 2

Answer:

sum of 2 complementary angles =90degrees

ratios are 2:1

let two angles be 2x and 1x

2x+1x=90

3x=90

x=90/3

x=30

so two angles are 2*30, 1*30

60 degrees and 30 degrees are the two angles
