All right, so you have to figure out theta to the nearest degree.
00:05
And so in order to solve for theta, we have to cancel out the tangent.
00:12
And to do that, we have to use the opposite operation.
00:15
So just like when you solved equations in algebra, to undo add, you had to subtract, to undo multiply, you had to divide, to undo squares, you had to do square roots.
00:26
To undo tangent, you have to use what's called the inverse tangent.
00:30
So to cancel that tangent, we use the inverse of tangent.
00:36
And so we are going to calculate the inverse tangent of 5 .6 -838...
