Question

if two angles of a quadrilateral are 40 and 110 and the other two are in ratio 3 :4 ,find the angles.

Answer 1

Let ratios be x
40+110+3x+4x= 360
7x= 360-150
7x= 210
x= 210/7
x= 30
Therefore
Angle 1 = 3*30
= 90
Second angle
4x
4*30
= 120

Answer 2

Hey...!!!

Angles are 40°, 110°, 3x and 4x
So,

40 + 110 + 3x + 4x = 360
150 + 7x = 360
7x = 360 - 150
7x = 210
X = 210/7
X = 30

So! The other angles are
( 30 * 3) = 90° and,
( 30 * 4) = 120°

Hope it helps...!!!
