Consider this right triangle with given measures.

9 cm

Step-by-step explanation:

We can use the Pythagorean theorem

a^2+b^2 = c^2

12^2+b^2 = 15^2

144 +b^2 = 225

Subtract 144 from each side

144-144+b^2 = 225-144

b^2 = 81

Take the square root of each side

sqrt(b^2) = sqrt(81)

b = 9

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

hope this is what you were asking for!
