Question

The sides of a triangle are in the ratio 3 : 4 : 5. State whether the triangle is right-angled or not.

Answer 1

Answer:

YES

Step-by-step explanation:

CUZ ,

IN THE RATIO 3:4:5, let the common factor be x

therefore, the sides are 3x,4x,5x

according to pythagoras, (3x)²+(4x)²=(5x)²

or 9x² + 16x²=25x²

or 25x²=25x²

Answer 2

Answer:

let the angles be 3x,4x,5x,

3x+4x+5x= 180

12x=180

x=15

3x=45

4x= 60

5x= 75

IT IS NOT A RIGHT ANGLE
