Question

Find the measure of all four angles of a parallelogram whose adjacent angles are in

the ratio1:3​

Answer 1

Answer:

Answer:Let the angles be x and 3x respectively.

Now , the sum of adjacent angles of a parallelogram = 180 deg.

Therefore ,

x + 3x = 180

4X= 180

x= 45

Hence the adjacent angles are 45 deg. And 45×3 = 135 deg.

The remaining angles = 45= 45 and 135=135 { opposite angles of parallelogram are equal )

Hence the four angles are 45, 45 , 135 and 135 degrees .
