Answer: B. 180°.
Step-by-step explanation: In the attached figure, GHIJ is a square and ABCDEF is a regular hexagon having common centre O.
A square is symmetric at a rotational angle of 90° and a regular hexagon is symmetric at a rotational angle of 60°.
So, to bring the image of the square and the hexagon back to the previous position, we need to find the LCM of both the angles.
LCM(60°,90°)=180°.
So, the correct option is B. 180°.

9 parallelograms
Step-by-step explanation:
Answer:
D)
<DEF = 1/2(236 - 124)
Step-by-step explanation:
<DEF = 1/2(236 - 124)
B. closer to 4 than to five
Because 40/9=4.44444
1/4 y = 13
y = 13 x 4
y = 52
answer is C. 52
