Question

A right triangle has legs that both measure 14 inches. What is the length of its hypotenuse to the nearest whole number?

Answer 1

20 inches!! a^2+b^2=c^2
14^2+14^2=392
square root of 392 is 19.79, round up and you got 20 inches

Answer 2

So, to find this answer, we want to use Pythagorean Theorem!

The formula for this theorem is: a²+b²=c².

· It's important to note that c² is always your hypotenuse, while a and b are your legs.

So, all we need to do is (1) plug in our values, (2) square them, (3) isolate them, and (4) find the square root of our final number!  

--------------------------------------------------------------------------------------------------------------

14²+14²=c²

14² = 196

We want to isolate our C, but we can't do that with the squared symbol, so in order to remove a squared symbol, we need to square root both sides.

196 = c²

√196 = 14

C = 14
