Question

Q12 One angle of a quadrilateral has measure
21°
and the measures of other three
angles are in the ratio 2:3:4. Find their
measures in degree and radian.​

Answer 1

Answer:

let the angles be 2x, 3xand 4x

1st angle is already given I. e 21 degree

Step-by-step explanation:

we know that sum of all Angle's in quadrilateral is 370 degree.

so we have

21+4x+3x+2x=360

9x=339

x= 37.67 degree

hence degrees are

1.21

2.150.68

3.75.34

4.113.01

now multiply these angles simultaneously by π\180
