Answer:
B and C
Step-by-step explanation:
2/3 = 6/9
and
1/2 = 4/8
The angle of rotation is the minimum angle in which you rotate a regular polygon such that the figure appears unchanged. The formula for that is dividing one angle of revolution by its number of sides.
Angle of Rotation = 360°/n
Angle of Rotation = 360°/72 = 5°
The answer is 60 because were subtracting in the equation but to find m we need to the opposite which is to add 53 plus 7 which is 60. To check your answer do 60-7 equals 53
Answer:
All three chose a valid first step toward solving the equation.
All approaches are algebraically correct
