If the sides of a triangle are in the ratio 3:4:5 and the perimeter of the triangle is 72 inches what are the lengths of the sides?

Thank you! That was a fast answer! What if it was angles? The angles of a triangles have the ratio 3:4:5 - would you say that 3x + 4x + 5x = 180 and then solve for x?

The answer is ----------

X=6

3x+4x+5x=72

solve for x, then you have it.

Yes, that would give you the angles, once you have solved for x, which is 15 degrees in this case.

Thank you so much!

If the sides of a triangle are in the ratio 3:4:5 and the perimeter of the triangle is 72 inches what is the longest length of the triangle?

X=6 for the one with 72cm and the

one for 180 cm is X=15

The sides of a scalene triangle are 6cm, 9cm and 13cm respectively. Find the area and perimeter of the triangle.

To find the lengths of the sides of the triangle, we can assign a variable to the ratio of the sides.

Let's assume the ratio is x, so the lengths of the sides would be 3x, 4x, and 5x.

We know that the perimeter of a triangle is the sum of all its sides, so we can set up an equation:

3x + 4x + 5x = 72

Simplifying the equation:

12x = 72

Dividing both sides of the equation by 12:

x = 6

Now we can find the lengths of the sides by substituting the value of x back into the ratio:

1st side: 3x = 3 * 6 = 18 inches
2nd side: 4x = 4 * 6 = 24 inches
3rd side: 5x = 5 * 6 = 30 inches

Therefore, the lengths of the sides of the triangle are 18 inches, 24 inches, and 30 inches.
