Question

Two comolementary angle are in ratio 7:2 find the angle

Answer 1

Answer:

Two angles are Complementary when they add up it's total is 90degrees

Two angels are in ratio 7:2

Sum of the ratio 7+2 = 9

Let X be the first angle and it's in ratio 7

so, X = 90*7/9

X = 70degrees

Let Y be the second angle and it's in ratio 2

so, Y = 90*2/9

Y = 20degrees

Hence, First angel is 70 degrees and second angel is 20 degrees

Step-by-step explanation:

To find the ratio add all the ratio

In above example we add up 7 and 2

For finding first ratio multiple the first ratio by total and divided it by total of ratio

In above example we do 90*7/9

and do it for other ratios
