If the legs of a right triangle are 7 inches and 3 inches. what is the length of the hypotenuse?

Using the formula for the Pythagorean theorem a^2 +b^2 = c^2, where a and b are the sides and c is the hypotenuse, we can rplace a and b with the side lengths and solve for c.

7^2 + 3^2 = c^2

49 + 9 = c^2

58 = c^2

c = √58 ( Length of hypotenuse)

If you need it as a decimal: √58 = 7.615773 ( Round answer as needed.)

false

step-by-step explanation:

it would open into a square depending on the type of envelope i’m not sure about the second part
