Answer:A) √3Step-by-step explanation:The tangent of an angle can be found by dividing the leg opposite the angle over the leg adjacent to it.So, we have to find them.The 30-60-90 rule says that in a right triangle with the angles 30°, 60° and 90°, the sides opposite those angles will have the ratio of 1:√3:2.That means the side adjacent to 60° is 2 units long and the one opposite is 2√3 units long.Dividing those two gives us (2√3)/2, which can be simplified to √3.
