    The inscribed angle = 1/2(the intercepted arc)

    For the second one I have no idea what QR and LN represent so can't help with that one.

    For #2, if they are congruent, then it means they are equal.

    Once you solve for x, plug that number in the x of QR.

    You shouldn't add 3x. You should subtract it. :)

    Like what Mertsj said, the formula is the inscribed angle = 1/2(the intercepted arc).

    Or if you don't want to deal with fractions,\[2\times m∠C=arc AB\]

    You flipped the arc and the angle.

    Do you know how to distribute 3 to 3x+5? What class are you taking?
