# Q.4.adjacent angles of a parallelogram are in the ratio 2:3 find the angles of the parallelogram ?? Q.5. adjacent angles of the parallelogram are (3x-40)degreesand (2x+20)degrees, find all the angles of the parallelogram ???

Asked by Kunwar Digvijay Singh Tanwar 15th March 2013, 2:22 PM
The sum of adjacent angles of a parallelogram is 180 degree since they are interior angles on the same side of the transverse between 2 parallel lines.

Q4. So, let the angles be 2x and 3x
2x+3x = 180
hence, 5x = 180
x = 36

So, the angles of the paralleogram are 2(36)  and 3(36) = 72 and 108 degree respectively. Also, opposite angles of a parallelogram are equal, so the angles would be 72, 108, 72, 108.

Q5.  Similarly, here
3x-40 + 2x+20 = 180
Hence, 5x = 200, x = 40
Hence, angles are 80, 100, 80, 100 degree respectively.
