The sum of the angles in a triangle are 180 degrees, correct?

anonymous · Answer

x is an angle, correct? In that case, thinking that two sides of the triangle are congruent should be a BIG clue

schrodinger · Answer

Given that the diagram gives us the angle of a triangle, of which we can safely assume the angles in it add up to 180 degrees, let's first start by subtracting the given angle from 180.

180 - 86 = 94.

? I was wondering why you thanked me. Did you figure it out or should I go on? Not exactly clear.

anonymous · Answer

no i mean thanks for helping me, cause some of my other questions have gone unanswered for hours.....

anonymous · Answer

ok so i got 47

schrodinger · Answer

Okay, lol. Your "ok.........." after sounded as if you had a problem. But yeah. If you've got two lines coming from the center of a circle, you can always assume that the two other angles are identical. e.g, you have 94 degrees left, since both angles are identical, you divide by two to get your answer.
