Question

Two angles are supplementary.If one of them is one-third of the other. Find the angles

Answer 1

Heya

Let see your answer !!!!

Let the other angle be x. Then,

its supplement = x/3

according to question ,

x + x/3 = 180

=> 3x + x/3 = 180

=> 4x/3 = 180

=> x = 180 × 3/4

=> x = 135

Hence , the other angle measures = 135°

and it's supplement = 135°/3 = 45°.








Thanks :))))

Answer 2

let the angels be x and y
supplementary angles =180.
and x=1/3y
and x+y=180
putting the value of x in the equation
1/3y+y=180
1+3/3y=180
4/3y=180
y=180x3/4
y=45x3=135.
x=180-135=45.
