Question

What is the answer to this

Answer 1

Answer:

c=15

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem to find the hypotenuse.

a^2 +b^2 =c^2

where a and b are the legs and c is the hypotenuse

9^2 +12^2 = c^2

81 +144 = c^2

225 = c^2

Take the square root of each side

sqrt(225) = sqrt(c^2)

15 = c

Answer 2

To answer this, you are trying to find C^2, which is the hypotenuse.
You can use Pythagorean Theorem to solve this problem, which is A^2+B^2=C^2.
When substituting, the equation becomes 9^2+12^2=C^2.
Which is then 81+144=C^2, and then 225=C^2.
$\sqrt{225} = 15$
The answer is 15.
