Question

the angles in a linear pair are in the ratio 5:7. find them.

Answer 1

let the angles be 5x and 7x
now,
by linear pair
5x+7x=180
12x =180
x=180/12
x=15
5x=15*5=75
7x=15*7=105
hope this helps

Answer 2

5x+7x=180 (linear pair)
12x= 180
x= 180/12
x=15
so, 5x=5×15=75
7x=7×15=105
may it will help you
