Question

2. Find the missing side length of the right
triangle below?

Answer 1

x=16

Explanation:

Use Pythagoras's Therom.

a^2+b^2=c^2

Insert the values.

12^2+x^2=20^2

Now simplify.

144 + x^2 = 400

Isolate x by subtracting 144 from both sides.

x^2= 400-144= 256

Take the square root of both sides.

x=16

Hope this helps!

Answer 2

The answer for the missing side length is 16

Explanation:

You have to use Pythagorean's Theorem
`a^2 + b^2 = c^2`

`c^2` is the hypotenuse, which is 20 in this case

`a^2` is the bottom, which is 12

and you have to solve for
`b^2`

So

`a^2 + b^2 = c^2`

`12^2 + b^2 = 20^2`

`b^2 = 20^2 - 12^2`

`b^2 = 400 -144`

`√(b^2) = √(256)` This cancels out the exponent

`b = 16`

That's the missing side length
