Can someone tell me what the radian value is for this number and how they got it?

Thanks

On a graph plot the point A(2,1)
Let C(2,0) be the point on the x-axis

x is the angle AOB and tan x = 1/2

Since angle x is not one of the special angles, you will have to use a calculator to find it (or trig tables from an old math textbook)

set your calculator to Radians,
enter "2nd" "tan" .5
or "shift" "tan" .5 depending on your calculator.

you should get appr. 0.4636
or 26.565º

.46

30

trig sucks

To find the radian value for the angle x, follow these steps:

1. Plot the point A(2,1) on a graph.
2. Let C(2,0) be the point on the x-axis.
3. Determine the value of tan(x) = 1/2.
4. Since the value of x is not one of the special angles, you will need to use a calculator to find it.
5. Set your calculator to radians mode.
6. Enter either "2nd" "tan" 0.5 or "shift" "tan" 0.5, depending on your calculator.
7. The result should be approximately 0.4636 radians.
8. Alternatively, the result can be expressed as approximately 26.565 degrees.

Please note that the specific instructions for using your calculator may vary, but the general steps remain the same.
