Answer:
Step-by-step explanation:
The way the triangle is laid out, BC is the hypotenuse, and AB is the side opposite <C. You hare given that the Sin<C = 1/2
If Sin<C = 1/2 then C = 30 degrees. It is part of the unit circle.
The tan (<30 degrees) = 1/sqrt(3) from the unit circle.
The cotangent of 30degrees = 1/tan(30) = sqrt(3)
cot(30) = sqrt(3) = 1.7321
