I look this question up on the internet and found out that the answer was 58, but could someone please explain how to get to the answer? I know that the angle is 46 degrees, so I used the supplementary angle to figure out 134 degrees and vertical angles to figure out the other two angles. After that I have no clue what to do.
The answer is 10, but could someone please explain this to me? i thought that a chord has two of its endpoints on the circle, so how can it be tangent to the circle?
Answer is 87, but could someone please explain this to me? I know that if a quadrilateral is inscribed inside of a circle, the opposite angles are supplementary.
I don't know the answer for this one, could someone please explain this to me. First of all, I don't understand how BAC can be an angle. If it is an angle, I have no clue how to solve it.
