Question

In a quadrilateral, if three angles are in the ratio 3:3:1 and one of the angel is 80. then find the other angle​

Answer 1

Answer:

Step-by-step explanation:

3x + 3x + x + 80 = 360

7x = 280

x = 280/7

x = 40

The angles are 120 ,120,40,80

Answer 2

SOLUTION;.....✍️
In Quadrilateral_,
Given, three angle in Ratio= 3:3:1
and One angle = 80°

Now,
let the angle be x

=3x+3x+1x+80= 360(Sum of all sides of Qua.)

= 7x+80°= 360°

= 7x= 360°-80°

= 7x= 280°

= x= 280°/7

=x= 40°

So,
1st angle= 3x= 3×40°= 120°
2nd angle= 3x= 3×40°= 120°
3rd angle = 1x= 1×40°= 40°
4th angle= 80°{given}
