Question

What is the measure of an angle whose sine is√3/2 ? 60 45 30

Answer 1

Answer:

60

Step-by-step explanation:

sin(theta) = sqrt(3)/2

On the calculator:

Press shift

Press sin

(It will show sin^-1)

Then enter sqrt(3)/2

Press =

It will give you an output of 60

Answer 2

Step-by-step explanation:

Step 1:  Find the answer

To find sine, that means we need to find the y-value where it equals √3/2.

If you know the unit circle, you know that the long side is √3/2 and the short side is 1/2.  So... in order to have the long side to be a y-value, that means that we need to have a long vertical triangle.  The angle that will fit this will be 60 degrees.

On you calculator, you should have a sin and you just type in something like this:  sin(60) and it should give you √3/2.

Answer:  Option A, 60
