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

5 inches
19 inches
20 inches
28 inches

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

x=11

Step-by-step explanation:

QRS~ TUV, so we have corresponding parts. RS/UV = RQ/UT (corresponding sides proportional)

substitute : 54/36 = 24/(x+5)  t

simplify and solve: 3/2 = 24/(x+5);  3(x+5) = 48 ;   x+5 = 16, x=11
