You use the Pythagorean theorem
.
Formula: a^2 + b^2 = c^2
<u>Solve for x:</u>
Take out exponent.
12^2 + x^2 = 20^2
Subtract 144 on both sides to get the variable alone.
144 + x = 400
-144         -144
You get the solution as 256. But you know it's bigger than the numbers given. So find the square root of 256.
x = 256
Which leaves you with:
x = 16
<u>Check:</u>
12^2 + 16^2 = 20^2
144 + 256 = 400
400 = 400
<u>Key:</u>
a = First shortest side (shorter side with the number smaller than side b and c)
b = Second shortest side (the number that is between side a's and c's number)
c = Third shortest side (longer side with the number larger than side a and b)

Answer:
Step-by-step explanation:
Since the two triangles are similar, you can use proportions to solve for the value of 

Now, just multiply 4 and 12.

Then divide that by 3.

Therefore,  .
