Question

please answer the question immediately question no 4​

Answer 1

let ratio of angle be x.

angle,

A=3x •••••••••1st

B=4x••••••••••2nd

C=6x••••••••••3rd

D=7x••••••••••4rth

we know that the sum of all angles in a quadrilateral is 360 degree,

so

angle a + Angle b + angle c + Angle b = 360 degree

hence,

3 x + 4 x + 6 x + 7 x = 360 degree

20x= 360 degree
x=
360 by 20
which is
x=18
put the value of x in all four equations we get
A=54
B=36
C=54
D=90
