Answer:
You use the pythagorean theorem given three angles in number two as it is a 30, 60, 90 triangle . The first one is a 60, 90 and a side and the third is a 60, 90 and a side as well. You should be able to find the equations for this easily enough.
Step-by-step explanation:
You have to find the lengths of x and y
You asked how to do it not for the answers to the questions
how many numbers are there and if there is more of the same number then that will be ur probability
i think that it is the third one
