Question

"x and y" are two supplementary angle. If supplementary angle of 'x' is equal to the half of complementary angle of 'y'. then find the ratio of 'x' and 'y'.

Answer 1

Answer:

x:y

=5:1

Step-by-step explanation:

supplementary angle of x = y. (eq.1)

supplementary angle of x = (90-y)/2. (eq.2)

On equating both equation,

y= (90-y)÷2

2y= 90-y

2y+y= 90

3y= 90

y= 90÷3

y = 30

so,

x+y= 180°

x+30 =180

x =180-30

x = 150°

Ratio of x and y,

x : y

150 : 30

5 : 1
