Answer:

15 units

The length of BC is 15 units.

Solution,

Hypotenuse(h)=?

perpendicular(p)=12

base(b)=9

Using Pythagoras theorem,


{h}^(2) = {p}^(2) + {b}^(2) \\ or \: {h}^(2) = {12}^(2) + {9}^(2) \\ or \: {h}^(2) = 12 * 12 + 9 * 9 \\ or \: {h}^(2) = 144 + 81 \\ or \: {h}^(2) = 225 \\ or \: h = √(225) \\ or \: h = \sqrt{ {15}^(2) } \\ h = 15

hope this helps...

Good luck on your assignment....
