Quadrilateral is a figure with for angles and sum of its angles equals 360 degree

In the above question the angels are given in the ratio form . Therefore let us choose the four angles as 1y , 2y, 3y, 4y ( same as the ratio given)

y is a random variable.

1y+2y+3y+4y =360 ( sum angle property)

10y=360

y=360÷10

y=36

Therefore the measure of four angles are 1×36,2×36, 3×36, 4×36

Which is the same as

36°, 72°,108°,144°
