Question

if the angle of a triangle are in the ratio 3:1:7 .what kind of a triangle it is?

Answer 1

it is acute angle triangle as any of it's angles will not exceed 90°.

Answer 2

It is a scalene triangle.

If the ratio are 3 : 1 : 6

Let the angles are

3x , x , 6x

Sum of the angels of triangle = 180

:. 3x + x + 6x = 180

10x = 180

x = 180 /10

x = 18

:. The angles are = 3x = 3 x 18 = 54

X = 18

6x = 6x18 = 108
