Question

In a quadrilateral three angles are in the ratio 3:3:1
and the fourth angle is 80'then find
the measures of other angle -​

Answer 1

Step-by-step explanation:

the sum of all angle in a quadrilateral is 360

According to question

let us take first angle be 3x

second be 3x , third angle to x and fourth angle is given that is 80.

3x+3x+x+80=360

7x+80=360

7x=280

x=40

hence first angle is 3x= 3*40=120

second angle is 3x=3*40=120

and third angle is x hence x =40
