What is the length of BC in the right triangle below?

Answer:
D
Step-by-step explanation:
u can use Pythagorean theorem a2 + b2 =c2. c2 is the length of the hypotenuse. plug in 3 for a and 15 for b. 3 squared plus 15 squared equals c squared. 9+225= c2. 234=c2. answer is D. the square root of 234
Answer:
D
Step-by-step explanation:
using Pythagoras theorem, the formulae is
|BC|²=|AC|²+|AB|²
|BC|²=15²+3²
|BC|²=225+9
|BC|²=234
|BC|=²√234
