Question

Sides of a triangle are in the ratio 3:4:5 and perimeter is 360 cm.what will be it's longest side​

Answer 1

Step-by-step explanation:

By the problem,

3x+4x+5x=360 cm

=> 12x=360 cm

=> x = 360/12

x=30

So the sides measure 90 cm, 120 cm and 150 cm.

Longest side = 150 cm.

Answer 2

Answer:

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

perimeter = sum of all sides

3x + 4x + 5x = 360

==> 12x = 360

==> x = 360/12

==> x = 30

therefore the sides are;

90 cm

120 cm

150 cm

longest side = 150 cm
