Question 560778: I'm given a triangle to solve using trigonometry basics in my honors geometry class, in my text book I have the length of the hypotenuse of a right triangle(4.5) and I have solved for all the angles(90 degrees by 26 degrees by 64 degrees) I do not know what trig function to use to find the missing 2 legs. I have more problems set up this way and would like to know how to solve this type of problem and not just the answer. THANKS!

We have a right triangle:



We can use either sine or cosine to find the other two lengths. If you recall the definition of sine, for example, we have





Then solve for a and b. Make sure your calculator is in degrees instead of radians.
