Question

two adjacent angles of a parallel gram are in a ratio 1:3 .find the measures of all the angles

Answer 1

Since opposite sides of paralellogram are Parallel
So,it's adjacent angles are suplementry

Let the first angle be a
Second angle = 3a

Now,
a+3a = 180
4a = 180
a= 45

First angle = 45 degree
Second angle = 135 degree
Third angle = 45 degree
Fourth angle = 135 degree


Hope it helps
