Question

In right triangle ABC, AB = 6, BC =12, and m

Answer 1

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

Answer 2

Cot(30) = sqrt(3). The correct answer is option A.
