Question

Two angles of a quadrilateral are 110degree pand 40 degree and the remaining two angles are in ratio 3:4 find the angles

Answer 1

Answer:

3:4=90:120

Step-by-step explanation:

let, 3=3x and 4=4x

110+40+3x+4x=360

150+7x=360

7x=360-150

7x=210

x=210/7

x=30

therefore 3x=90 and 4x=120
