Answer:

measure angle FP is 62°

Explanation:

The angle R inscribes the arc FQ, so using the property of inscribed angles in a circle, we have that:

m∠R = mFQ / 2

The arc FQ is the sum of the arcs FP and PQ, so we have:

mFQ = mFP + mPQ = 11x + 7 + 60 = 11x + 67

Now, with the first equation, we have:


12x + 1 = (11x + 67) / 2\\\\24x + 2 = 11x + 67\\\\13x = 65\\\\x = 5^\circ

So we have that mFP


= 11x + 7 \\\\= 55 + 7 \\\\= 62^\circ
