Question

(i) Two complementary angles are in the ratio 2 : 3. Find them.
(ii) Two supplementary angles are in the ratio of 7:5. Find them. Full explanation please
​

Answer 1

Answer:

(i) let the two angles be 2x and 3x

ATQ, 2x+3x=90

5x=90

x=90/5=18

therefore,2x=2×18=36

3x=3×18=54

(ii) let the two angles be 7x and 5x

ATQ, 7x+5x=180

12x=180

x=180/12=15

therefore, 7x=7×15=105

5x=5×15=75
