<u>Part 1</u>

By the inscribed angle theorem, arc PA measures 62 degrees.

<u>Part 2</u>

Angles inscribed in the same arc are congruent, so angle PRA measures 31 degrees.

<u>Part 3</u>

Diameters form semicircles, and the arc of a semicircle measures 180 degrees, so arc PAR measures 180 degrees.

<u>Part 4</u>

Subtracting arc PA from arc PAR, we get arc AR measures 118 degrees.
