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
