1 answer:
The answer would be x = 45 and y = 15. This is because congruent sides have congruent angles. If this is the case, you can fill in your triangle like this. All three sides of a triangle add up to 180 degrees. So, you set up your equation like this. Now you should have two different equations that add up to 180. Using the elimination method, you can solve this double variable equation. You can solve for any variable first but here I choose x. Now that you found x, you can substitute it back into one of your original equation to find y. I hope it helps!
