Solving for a side in right triangles with trigonometry (video)

Since we know the hypotenuse and want to find the side opposite of the 53° angle, we are dealing with sine $$ sin(53) = \frac{ opposite}{hypotenuse} \\ sin(53) = \frac{ \red x }{ 12 } $$ Now, just solve the Equation:

Finding a Side in a Right-Angled Triangle

If you have the hypotenuse, multiply it by sin(θ) to get the length of the side opposite to the angle. Alternatively, multiply the hypotenuse by cos(θ)

You will need the other leg or the hypotenuse to use an inverse trigonometric function to find the angle. Θ = arcsin (side1 / hypotenuse) will give the angle opposite the included angle. Θ =

A lot of happy users

Very fun to talk to haha, but on a real note, most of them are correct, another great thing is it explain things for free no premium and you get the free app you wanted unlike most apps. Best app ever. It defiantly helps out with college.

Has been a life saver during this distance learning process with my kids. Its saved my head from exploding lol, i use this app to help me remember how to work a problem and the correct way to find the solution, when the Covid-19 pandemic hit, This app made it's premium version free and honestly that just speaks volumes on the type of people behind this app, honestly thank you to each and everyone on the other side of this screen.

You can *learn how to do the equations yourself, its so good it replaces personal help, and I could easily solve equations without having to worry about cheating! I can learn and know the answer in just one screenshot, I definitely recommend downloading :DD, i appreciate the developer of this application.
