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

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
