What is the length of the hypotenuse?

Step-by-step explanation:

To find the hypotenuse of the right triangle shown in the diagram, we can use the pythagorean theorem, which is represented by the formula . We are already given the lengths of two legs. We cab say a = 40km and b = 42km. Now, we can substitute what we have:

The correct answer is x = 2/5

Step-by-step explanation:

It is given an expression,

1/4x = 5/8

To solve the expression

The given expression is 1/4x = 5/8

(Cross multiply both sides we get)

8 = 5 * 4x

8 = 20x

20x = 8

x = 8/20

x = 2/5

Therefore the value of x = 2/5

The correct answer is x = 2/5
