Answer 1

hope this will help you

Answer 2

$\fbox {ANSWER}$

●...........................................................●

Ratio of the angles of triangle = 1:2:3

Let the angles of the triangle be ,

1x , 2x and 3x

Now ,

1x + 2x + 3x = 180°

(As sum of all three angles of a triangle is 180°)

6x = 180°

x = 180/6

x = 30°

So,

1st angle of the triangle = 1x = 1×30

= 30°

2nd angle of the triangle = 2x = 2×30

= 60°

3rd angle of the triangle = 3x = 3×30

= 90°
