Question

If the perimeter of the triangle is 60, what is the value of y?

Answer 1

• y = 5

Explanation:

Given:

• In the right triangle the hypotenuse is 5y, one leg is 4y, the other leg is missing

Missing side of the triangle is:

• √(5y)² - (4y)² =
• √(3y)² =
• 3y

Perimeter is 60:

• 3y + 4y + 5y = 60
• 12y = 60
• y = 60/12
• y = 5
