Sally drew a circle with right triangle PRQ inscribed in it, as shown below: The figure shows a circle with points P, Q, and R on it forming an inscribed triangle. Side PQ is a chord through the center and angle R is a right angle. Arc QR measures 40 degrees. If the measure of arc QR is 40°, what is the measure of angle PQR? 20° 40° 50° 70°

20 degrees

Step-by-step explanation:

took the test

70

Step-by-step explanation:

I took the test, and here's the math.

1/2 (40; the given angle) = 20

PRQ is a right triangle, so it has a 90-degree angle.

All the angles added = 180

20 + 90 = 110

180 - 110 = 70

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
