to find what X is intention of X equals square root of 3/3. Now, like traditional graphing calculator, you're gonna type the sea in, ask second, and then you're gonna type in your tangent in verse, which is that with the tangent with the negative one over it. And this is right above my tangent key and I parentheses is gonna pop up and you're gonna probably need to put another parentheses for your square root of three divided by three. So I pulled up in online graphing calculator to type this in so we can see the Onley main differences. We're not gonna be a second, but so here we are And let's pull up our you see all of our trig functions. So we're gonna use the inverse of tangent and a parenthesis is already popped up. I'm gonna since we're doing square root of three, I'm gonna put another parentheses. I put my square to three in there, and then I'm gonna move my arrow button over. So the calculator knows I'm done with the square road and we're gonna divide square to three by three. And that tells me that the inverse of square root of 3/3 is 30 degrees, so this means that X equals 30 degrees, or the tangent of 30 degrees is square root of 3/3.
