okkkkkkkkk wait but pls mark as brainlist

Answer 2

Step-by-step explanation:

take the angle of the triangle = x

3= 3x

7- 7x

10- 10x

3x+ 7x + 10x = 180°

20x = 180°

x = 180÷ 20

x = 9

so,

3x = 3x9

= 27°

7x = 7x9

= 63

10x = 10x9

=90°

so, we get an angle that is equal to 90°

hence proved this is a right angled triangle
