Question

if the angle of a quadrileteral
ratio 5:8:11: 12, find the angles​

Answer 1

Answer:

let the angles be 5x ,8x,11x and 12x

according to the angle sum property of a quadrilateral, we know that the sum of measure of all the angles of a quadrilateral is always 360°

so

5x+8x+11x+12x= 360°

36x=360°

x= 360/36

x= 10

so the angles are

5x= 5×10

=50°

8x=8×10

=80°

11x= 11×10

=110°

12x=12×10

=120°

answer: 50°, 80°,110° and 120°
