Answer:

2.3

Step-by-step explanation:

Using SOH CAH TOA, we can label CB as the alternate side seeing as it's opposite to the known angle 50 degrees. We know AB is the hypotenuse since it's the longest side. Therefore CA must be the alternate side.

Since we want to know BC, and we know information about AB, we need to use the use of the hypotenuse and the opposite. In SOH CAH TOA, SOH uses both of these.

Using S O H, we understand that sin(50) * 3 = CB

Therefore CB = 2.3 to 1 decimal place.
