Answer:

About 7 units

Step-by-step explanation:

Since it is a right triangle we apply Pythagoras theorem

$a {}^{2} + b {}^{2} = c {}^{2}$

a= square root(144 - 100)

a = about 7

Answer:

A

Step-by-step explanation:

We can use the Pythagorean Theorem:

$a^2+b^2=c^2$ , where a and b are the two legs and c is the hypotenuse.

Plug in what we know:

$(10)^2+b^2=(12)^2$

$100+b^2=144$

$b^2=44$

$b=\sqrt{44}\approx 6.63\approx7$
