Question 7

A regular decagon has ten equal sides and ten equal angles. When a regular decagon is drawn inside (inscribed in) a circle, the radii form equal angles at the center. Find the number of degrees in each angle at the center.
A) 20
B) 36
C) 45
D) 60

Accepted Answer

The total degrees in a circle is 360 degrees. Since a regular decagon has 10 equal sides, and the radii form equal angles at the center, dividing 360 degrees by 10 gives each central angle as 36 degrees.

Question 8

What part of a circle is a 90 degree angle?
A) 1/6
B) 1/4
C) 1/3
D) 1/2

Accepted Answer

A circle is 360 degrees, so a 90 degree angle represents 1/4 of a circle.

Question 9

How many degrees are in an eighth of a circle?
A) 45
B) 90
C) 120
D) 180

Accepted Answer

A circle has 360 degrees, so an eighth of a circle is 360/8 = 45 degrees.

Question 10

In making a gasket, a mechanic lays off 18 equally spaced holes on the circumference. Find the number of degrees between the centers of the holes.
A) 20
B) 30
C) 36
D) 45

Accepted Answer

The answer of In making a gasket, a mechanic lays...
