hmm i thought i knew how to do this but now im confused : 3

Answer 3

I know!

Answer 4

So, since the two sides (21) are equal, it's an iscosceles triangle, meaning those bottom two angles will be the same.

Answer 5

There are 180 degrees in a triangle, so 180-38=142. That's the measure of the bottom two angles combined. Divide that by 2 to get x: 142/2=71. You can check by adding them all together:
71+71+38=180
bada bing!

Answer 6

x=71 degrees
