3. The angles of a quadrilateral are in the ratio of 1:1:1: 3. Find
(a) all the angles.
(b) Is it possible to have such angles? Why or why not?

Answer 1

Answer:

2].....

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

sum of the two angels is 136°

then other two angles are equal so,

A\q

x+x+136°=360°

2x = (360-136)°

2x = 224

x = 112

hence, the other two angles are 112°and 112°

3]......

let all the angles are x, x,x,3x

then, 6x = 360°

x =60°

a) All angles are 60°,60°,60°,180°

b) No, it is not possible to have a such angles because it's one angle is 180° which can not formed closed figure
