Question

What is the length of the hypotenuse of the triangle when x=7​?

Answer 1

Answer:
Length of Hypotenuse
Decimal Form: 68.609
Radical Form: 28 * sqrt(5)

Answer 2

`\approx63`

Explanation:

Let's start by finding the length of each leg.

`7x+7=7(7)+7=49+7=56\\4x=4(7)=28`

Now, we can use the Pythagorean Theorem to find the length of the hypotenuse.

`a^2+b^2=c^2`

`28^2+56^2=c^2\\784+3136=c^2\\3920=c^2`

Take the square root of both sides:

`c\approx63`
