Anna [14]

Answer:

<h2>15 units</h2>

The length of BC is 15 units.

Solution,

Hypotenuse(h)=?

perpendicular(p)=12

base(b)=9

Using Pythagoras theorem,

${h}^{2} = {p}^{2} + {b}^{2} \\ or \: {h}^{2} = {12}^{2} + {9}^{2} \\ or \: {h}^{2} = 12 \times 12 + 9 \times 9 \\ or \: {h}^{2} = 144 + 81 \\ or \: {h}^{2} = 225 \\ or \: h = \sqrt{225} \\ or \: h = \sqrt{ {15}^{2} } \\ h = 15$

hope this helps...
