Question

if three angle of a triangle are in the ratio 3:7:10,show that triangle is right-angle​

Answer 1

3,7,10

According to pythagorean theorem

(Hy)2=(P)2+(B)2

(10)2=(7)2+(3)2

100=49+9

100=59

Therefore this triangle is not a right angled triangle

Answer 2

Answer:

Let the angles of a triangle = 3x , 7x and 10x

We know that ,

The sum of all angles of a triangle = 180°

3x + 7x + 10x = 180 °

20 x = 180°

X = 180°/20

X = 9°Hence , the angles of a triangle = 3x9° , 7x9° , 10x9°

= 27° , 63° , 90 °

Here , one angle of triangle is 90°

So, this triangle is Right-Angled triangle.
