Answer 2

Answer:

Let x be the common multiple for this ratio.

As we know that the interior sum of triangle is 180°.

So the equation will be,

1x + 2x + 7x = 180°

10x = 180°

x = 180/10

x = 18

So,

1st angle = 1x = 1(18) = 18°

2nd angle = 2x = 2(18) = 36°

3rd angle = 7x = 7(18) = 126 °

Since all angle are different, therefore it is a scalene triangle.
