The perimeter of a triangle is 74 inches. The length of the first side is twice the length of the second side. The third side is 4 inches more than the first side . Find the length of each side of a triangle

Perimeter of a triangle = 74 inches.

the length of each side of a triangle

Let the length of the first side be x inches.

Hence,

• 2 * Length of the second side = x inches

→ Length of the second side = (x/2) inches

• Length of the third side = (x + 4) inches.

We know that,

Perimeter of a triangle = Sum of its three sides.

Hence,

→ 74 = x + x/2 + x + 4

→ 74 = (2x + x + 2x + 8)/2

→ 74 * 2 = 5x + 8

→ 148 - 8 = 5x

→ 140/5 = x

→ x = 28

Therefore,

Length of first side = x = 28 inches.

Length of second side = x/2 = 28/2 = 14 inches.

Length of third side = x + 4 = 28 + 4 = 32 inches.

Verification:-

Sum of the three sides = 74 inches

→ 28 + 14 + 32 = 74

→ 74 = 74

Hence, verified

I hope it will help you.

→ 74 = x + x/2 + x + 4

→ 74 = (2x + x + 2x + 8)/2

→ 74 * 2 = 5x + 8

→ 148 - 8 = 5x

→ 140/5 = x

→ x = 28

Therefore,

Length of first side = x = 28 inches.

Length of second side = x/2 = 28/2 = 14 inches.

Length of third side = x + 4 = 28 + 4 = 32 inches.

side xy = 10

sin(x) = 4/5

cos(x) = 3/5

tan(x) = 4/3
