This is JSS geometry.

D) 60deg. Angles in a circle = 360. Since there are 12 chords, angle at the inside of each chord triangle is 30, the sides of the chords 75 each (angle inside triangle = 180). Including the ones on the other coin = 75×4 = 300. So x is 60. (Angle round a circle is 360deg)

Very simple 50 center = 50 degrees

That area forms an equilateral triangle (three equal sides.) Each angle of a triangle is 60°.
X= 60°

Total angles in a circle = 360
Number of sides = 12
X = 360 ÷ 12
X = 30
Therefore,angle x is equals 30 degrees.

By Australian students, I think you mean the Junior Secondary School equivalents?

Boss, I think we are looking for the angle between the coins. Don't you think?

60 degrees.
Each angle of a polygon = 180(n - 2)/n
For 12-sided polygon, each angle
= 180 (12 - 2)/12 = 150 deg
X = 360 - (150 + 150) = 60

Obviously a polygon. A circle doesn't have sides
