Question

in a triangle value of angles are integers which of the following cannot be proportion for their measures?
1.)1:2:3 2)3:4:5 3) 5:6:7 4)6:7:8 ​

Answer 1

Answer:

6:7:8

Step-by-step explanation:

6:7:8 can't be correct proportion of angles because-

Let the angles of triangle= 6x, 7x, 8x

6x + 7x + 8x= 180° (ASP of triangle)

21x= 180

x= 180/21

Since, 180 is not completely divisible by 21. Therefore, 6:7:8 can't be the correct measures of a triangle
