Question

Hi! Could someone pleaseeeeeeee help me!!

If the legs of a right triangle have lengths of 6 inches and 8 inches, what is the length of the hypotenuse in inches?
11
13
10
16

I have 3 other questions like this, and i need someone to explain how to do this so i can answer them all correctly while understanding!

Answer 1

Pythagorean theorem is: A^2 + B^2 = C^2
so: 6^2 + 8^2 then take the sqrt of that and there is your answer

Answer 2

Use Pythagoras theorem.
Take
AB = 8 inches
BC = 6 inches
AC = ?
So,
According to pythagoras theorem,
AB^2 + BC^2 = AC^2
So, put their values,
8^2 + 6^2 = AC^2
64 + 36 = 100 = AC^2
Take square root of 100, which is 10.
So, AC = 10 inches

So your answer is 10.

Answer 3

What happens if you multiply every side of a 3:4:5 triangle by 2?
