Question

13. If an angle of a parallelogram is 4/5 of it adjacent angle, then find the
measures of all the angles of the parallelogram​

Answer 1

Step-by-step explanation:

One angle =4x/5

Adjacent angle = x/5

Pair of linear equation

4x/5 + x/5 =180°

5x/5 =180°

x = 180°

One angle = 4/5 ×180° = 4×36° =144°

Adjacent angle = 180°/5 = 36°
