Question

If all the sides of a triangle are in the ratio 5:3:4 prove that it is a angle triangle​

Answer 1

Answer:

The sides of a triangle are in the ratio 3:4:5

let the sides of triangle is 3x ,4x and 5x

As per Pythagoras theorem

(5x)

2

=(4x)

2

+(3x)

2

⇒25x

2

=16x

2

+9x

2

⇒25x

2

=25x

2

So this triangle is right angle triangle

Then one angle 90

0

and other angles total is 90

0

Then greatest angle is 90

0
