Question

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

Answer 1

Answer:

x=16

Step-by-step explanation:

use the Pythagorean theorem.

$\sqrt{a^{2}+b^2$= $c^{2}$          Another way, you can do the problem is that you can see

$\sqrt{12^2+b^2$= $20^{2}$     that 12 divided by 4 is 3 and 20 divided by 4 is 5, which is

144+b^2=400     the two numbers from the special 3,4,5 triangle, and since

-144        -144      you have figured that much out, you can multiply 4*4 and

------------------------ get 16.

      b^2=256

$\sqrt{256\\}$ = 16
