Question

if two complementary angles are in the ratio 2:7 find the angles​

Answer 1

Answer:

20 degree and 70 degree

Step-by-step explanation:

As we know complementary angles add up to 90 degree

2:7

= 2+7

= 9

= 90 / 9

= 10

= 2:7 x 10

= 20:70

= 20 degree and 70 degree

Answer 2

Ratio of the angles = 2:7

So , let the angles be 2x and 7x.

Now, acc. to the Question,

2x+7x=90

9x=90

x=10

2×10=20

7×10=70

So the 2 angels are 20° and 70°
