Question

two supplementary angle are in ratio of 7:5. Find them ​

Answer 1

Answer:

Hope it's helpful for you

Step-by-step explanation:

let one angle be 7x and another be 5x where x is a common multiple

now 7x + 5x = 180

12x = 180

x= 180/12

x= 15

therefore one angle is 7x = 7×15=105°

another angle is 5x = 5×15=75°

Answer 2

Step-by-step explanation:

Let the two angles be 7x and 5x

the sum of supplementary angles is 180

7x + 5x = 180

12x = 180

x = 180/12

= 15

then,

7x = 7 * 15 = 105

5x = 5 * 15 = 75

hence the 2 angles are 105 and 75
