Step-by-step explanation: To solve for the side BC we can find the tangent (TAN) of 41 degrees. Since the tangent of an angle is equal to the opposite side over adjacent, we can set up an equation that looks like this, assigning side BC to be x:
tan(41)= x/16
0.1606567=x/16 <---- Use calculator to find tan(41)
0.1606567(16)=x/16(16) <---- Multiply each side by 16
