The sum of adjacent angles is 180 degrees,
let the smaller angle be x,
then the larger angle is 2x,
compose and solve the equation:
x + 2x = 180;
3x = 180;
x = 60;
the smaller angle is 60 degrees,
find a larger angle:
60 times 2 = 120 degrees
larger – 120 degrees.
answer: the larger angle is 120 degrees
