Question

The value of β is:A)60ºB)45ºC)90ºD)30ºE)75º​

Answer 1

Answer:

A

Step-by-step explanation:

To solve this problem, it is best to identify the sides (opposite, adjacent, hypotenuse) in terms of β. Since the adjacent side of β is 3 and the hypotenuse is 6, we know that cos(β) = 3/6 = 1/2. That means β = 60º, which is choice A.
