Triangle abc is isosceles, with AB = AC. Determine the measures of angles x and y. My triangle has 3 sides and is 130 degrees exterior to y. So far I found the y is 180-130=50 but I have trouble finding the x. Can you help me please?
Come on you need to think a bit. You found y which is great! Now can you figure out what the other two angles equal? Think Isosceles! Then play the same game you used to find y in order to find x.
