Question

if the adjacent angle of a parallelogram are in the ratio 5:4 find its all four angles.

Answer 1

Sum of adjacent angles of a parallelogram is equal to 180°

So, 5x + 7x  = 180
12x = 180
x = 15

All the angles are --->
5x = 15 x 5 = 75°
7x = 15 x 7 = 105°


The other 2 angles are also 75° and 105°.

Hence, your required answer is 75°,105°,75°,105°

Hope This Helps You!

Answer 2

Let the ratio of their angles be 5x and 4 X.
Then,
two angles will be 100 degree and two will be 80 degree.
