Question

The measures of two adjacent angles of a parallelogram
are in the ratio of 5:13. Find the measure of all its
angles.​

Answer 1

Step-by-step explanation:

let angles be a, b, c, d

a and b are adjacent angels

consider a=5x and b=13x

As adjacent angles of parallelogram are supplementary

so a+b=180°

5x + 13x = 180°

18x = 180°

x = 180°/18

x= 10°

As opposite angels in parallelogram are equal

so, a = c = 5x = 5×10 = 50°

b = d = 13x = 13×10 = 130°
