Question 4 multiple choice worth 6 points)

alex drew a circle with right triangle prq inscribed in it, as shown below:
if the measure of arc qr is 80°, what is the measure of angle pqr?
50°
40°
80°
70°

50°

Step-by-step explanation:

The diagram shows the arc RQ with the measure of 80°, this means the central angle ROQ (where O is the center of the circle) has the same measure of 80°. Angle QPR is inscribed angle subtended on the arc RQ. Its measure is half of the measure of the central angle QOR, so

In right triangle PQR, the sum of two acute angles is 90°, so

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
