Answer:
m<AIR = 90 deg
Step-by-step explanation:
I assume the problem contains an error, and that AR is a diameter, not AC.
Look at the diameter of the circle, AR. It passes through the center of the circle, C. You can think of the two radii of the circle, CR and CA, as sides of angle RCA. Since AR is a diameter, and AR is a segment which is part of line AR, rays CR and CA are sides of an angle that lie on a line. That makes the measure of angle RCA 180 deg. Angle RCA is a central angle of circle C since its vertex is the center of the circle.
Angle AIR is an inscribed angle in circle C since its vertex is on the circle itself. If an inscribed angle and a central angle intercept the circle at the same two points, then the measure of the inscribed angle is half the measure of the central angle.
m<AIR = (1/2)m<RCA = (1/2) * 180 = 90
m<AIR = 90 deg
Answer:
m > 2
Step-by-step explanation:
Since it is an open dot, it is not greater than or equal to, but rather just greater than.
Then, since the arrow goes to the right, the equation is greater than.
Answer:
Graph A.
Step-by-step explanation:
When Johnny starts moving <em>more </em>lawns, this means, in fewer weeks, he will have more total lawns mowed. We can see on the first graph, the blue line shows an increase of lawns mowed with fewer weeks.
Answer:
9. The scale factor is 1.5.
10. scale factor = 0.75
the missing side is 9m
Step-by-step explanation:
9. 3/2 = 1.5
9/6 = 1.5
6/4 = 1.5
10. 12/16 = 0.75
12*0.75 = 9
