Question

13. If a pair of complementary angles are in the ratio 3:7 then find the bigger angle. ​

Answer 1

Step-by-step explanation:

sum of complementary angle = 90°

take angle =x

then a=3x b=7x

=3x+7x=90°

=10x=90

=x=90/10

=x=9

now a=3x=3×9=27°

b=7x=7×9=63°

so second angle which is 63° is greater

Answer 2

Answer:

7x=7x9=63

Step-by-step explanation:

∆let the angles be 7x and 3x

because, complementary angles is 90°.

7x + 3x =90°

10x = 90°

x=90/10

x=9
