Question

If two angles are supplementary and one angle is 30° less than twice the other. find the angles.

Answer 1

Step-by-step explanation:

let the angles be x and y

ATQ;

x+y=180.........1

and

y=2x -30.......2

putting the value of y in equation 1

x+2x-30=180

3x =210

[ x=70. ]

from equation 1

y=180-70

[ y=110. ]
