## evergirl 3 years ago In the figure above, if A is the center of the circle, what is the value of x?

It would be cool if there was a figure above. :L

And here are the choices: 31 37 47 54 59

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

5. L.T.

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

6. Schrodinger

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.

Thank you!

8. evergirl

ok............

9. Schrodinger

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

10. evergirl

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

11. evergirl

ok so i got 47

12. Schrodinger

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.

Thanks again!

No problem. Good luck.
