im trying to find the angle of a triangle using the sides. but i dont know how on this calculator, usually when i use the one i have i use 2nd sine(16/20) (ex)
+23247 For your example: first press the (2nd) key. This will turn the (sin) key into (asin). Press this key, then enter the numbers: 16/20 and press the equal (=) sign. This will give you the size of the angle.
"asin" means "arcsine" which is inverse sine, what you want.
Similarly, for cos and tan.
