The perimeter of the triangle shown is 30 inches. What is the length of the longest side of the triangle
Simora [160]

Answer:

The length of the longest side of the triangle is 13 inches

Step-by-step explanation:

step 1

Find the value of x

we know that

The perimeter of triangle is equal to the sum of its three length sides

so

P=x+(2x+3)+(4x-8)

P=(7x-5) \ in

we have

P=30\ in

substitute

30=(7x-5)

solve for x

7x=30+5\\7x=35\\x=5

step 2

Find the length of the longest side of the triangle

Remember that in a right triangle, the longest side is the hypotenuse

so

(2x+3) is the longest side

substitute the value of x

2(5)+3=13\ in
