There is no x in this picture, but if you want to find the angle θ, note that you have a right-angled triangle with hypotenuse 17 and the side oposite θ is 10, so we have sin θ = opp/hyp = 10/17. So θ = 36.0° to 1 d.p.

Do you know trig functions? you can use either tangent, sine, or cosine. and you will need to know SOH CAH TOA. It stands for sine equals to opposite side over hypotenuse, cosine equals to adjacent side over hypotenuse, and tangent equals to opposite side over adjacent side. these are just things you need to memorize. oh and a little note.. the adjacent side can never be the hypotenuse... hypotenuse is the longest side of the triangle. So.. don't think that the adjacent side is the hypotenuse and vice versa. Justify the hypotenuse first then the adjacent will be the other side that is close to the angle. So from the given information or triangle, from the "x" degree the problem has given you the opposite and hypotenuse right? not the adjacent.. cause it's the longest side of the traingle. now here comes the algebra part of the problem. since you have the opposite and hypotenuse.. from the SOH CAH TOA thing i gave you which trig function can you use? Hm.. I'll choose Sine function right? then.. you will do sin (x)= 10 (opposite) / 17 (hypotenuse). Just use your calculator to divide 10 by 17. Don't estimate your value anything here... from here just press 2nd sine or just find the inverse of sine on your calculator to find the degree. oh.. and make sure you are in the DEGREE mode okay? I got 36.03187907. What did you get? if you have any questions.. feel free to email me at mashi_cutie@hotmail.com

sine of theta = opposite over hypotenuse..that will allow you to solve for theta....can solve for third side using sum of squares also......
