The circle below is divided into 12 equal parts.
What is the measure of the angle shown by the shaded section?
A.
30°
B.
60°
C.
40°
D.
45°
45
well, 360/12 = 30
but you don't say how many parts are shaded ...
66 + 72 =
A. 35
B. 66
C. 138
D. 122
i love this and the is c
To find the measure of the angle shown by the shaded section, we need to determine the size of each of the 12 equal parts.
Since the circle is divided into 12 equal parts, we can conclude that the central angle for each part is 360°/12 = 30°. This is because the sum of the central angles in a circle is always 360°.
Since the shaded section covers 1 of the 12 equal parts, the angle shown by the shaded section is simply the central angle for that one part, which is 30°.
Therefore, the answer is A. 30°.
