The sum of two adjacent angles is 140 if one angle is thrice that of the other.find the two angles

2 adjacent angles=140

Let us take the 2 numbers as x and y.
x+y=140
x=3y
Then 3y+y=140
4y=140
y=140/ 4
 It equals 35.

So, 1 angle is 35. Then the other angle is 140-35=105.

THE ANSWER IS 35 AND 105.

Hope this help!
