27 degrees

Can you explain it to me?

OpenStudy (anonymous):

yes. Since it's an isosceles triangle, the two lower angles would be equal. So they are both 63 degrees. What does that make the top angle? (There are a total of 180 degrees in a triangle.)

OpenStudy (anonymous):

180-63=117? Then what?

OpenStudy (anonymous):

No, there are two angles of 63 degrees each. So do 180-2(63).

OpenStudy (anonymous):

Wait I think I got it. 63*2=126 180-126=54 54/2=27 Did I do it right?

OpenStudy (anonymous):

Yes!
