Question

three angles of a quadrilateral are in the ratio 4 is to 3 is to 5 the difference between the greatest and the smallest angle is 42 degree find all the four angles of the quadrilateral

Answer 1

Let the angles are 4x , 3x ,5x

5x - 3x = 42
x= 21

Now angles are 4x21 = 84
3×21 = 63
5×21= 105

Sum of angles of quadrilateral are 360

84 + 63 + 105 +d = 360
d = 360-252
d = 108
All the angles are

a= 84, b= 63, c= 105,d= 108

Answer 2

there are two cases in wgich the second xase is true and the value of x is 21
