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

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

    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.

    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.
