PLEASE GEOMETRY HELP!! FIND THE LENGTH OF ARC PQR. EXPLAIN PLEASE!! BOGUS ANSWERS REPORTED

Answer 1

First we need to find the measurement of arc PQ.

And sum of measurement of all arc angles is 360 degree.

Let measurement of arc PQ is x degree.

Therefore, we get

$150+73+x+65=360 \\ 288+x =360 \\ x =360-288=72$

So measurement of arc PQ is 72.

And measurement of arc PQR is the sum of the measurement of arc PQ and QR.

That is

$m \ PQR = 72 +65 = 137$

measurement of Arc PQR = 137 degree= 2.39 radian

And radius is 6.48 inches

And arc length is the product of radius and central angle in radians .

That is

$PQR= 6.48*2.39=15.5 inches$
