complementary angles are in
the ratio 2:7
​

Answer 1

Step-by-step explanation:

let ratio be = 2x and 7x

now as we know complementary angles is of 90 degree so

2x +7x =90

9x=90

x=90/9

x=10

so 1st angle is = 2x= 2×10=20 degree

2nd angle is =7x= 7×10=70 degree

hope it may help you plz mark as brainlist
