Please help me with this math problem! I'm really confused.
MissTica

Answer:

48

Step-by-step explanation:

You will be using the  Pythagorean theorem for this problem. assuming the bigger triangle is double the size of the smaller triangle on the right, we would first plug in the numbers for the smaller triangle: 16^{2}  + B = 27^{2} which would come out to  21.7. then we could say that since like i said before the bigger triangle is double the other one, the bottom side of the triangle would be 32 (16 + 16) and would use the pythagorean theorem again, giving us our answer.
