The ratios of the measures of the angles in triangle XYYZ is 7:13:16. Find the measures of the angles
kirza4 [7]

Answer:

let the angles be 7x , 13x , 16x

7x + 13x + 16x = 180 ( sum of angles in a triangle is 180 degree)

36x = 180

x = 180 / 36

x = 5

therefore the angles are:

7 X 5 = 35 degree

13 X 5 =  65 degree

16 x 5 =  80 degree

plz mark me as the brainliest
