Question

Two adjacent angles of a parallelogram are in a ratio 1:3.find the angles?

Answer 1

we know that sum of the adjacent angles of a parallelogram are supplementary
therefore,
1x +3x =180
4x = 180
X= 180/4
X=45
3x =45*3=135
hope it helps and mark me brainliest answer

Answer 2

Let us take the given ratio be 1x:3x.

Sum of adjacent angles of a llgm = 180°.

Atq, x + 3x = 180°.

or 4x = 180°.

or x = 180°/4.

Therefore x = 45°.

So, 1st angle = 1x = 45°.

and 2nd angle = 3x = 45°× 3 = 135°.
