Write an expression describing all the angles that are coterminal with 72° . (Please use the variable "k" in your answer)
72+360 is the answer
To find all the angles that are coterminal with 72°, we can add or subtract a multiple of 360° to 72°.
So the expression describing all the angles that are coterminal with 72° would be:
72° + 360°k
where k is an integer representing the number of complete revolutions added or subtracted from the original angle.
To find all the angles that are coterminal with 72°, we need to add or subtract whole multiples of 360°. The formula for coterminal angles is given by:
θ = 72° + k * 360°,
where k is an integer representing the number of complete revolutions around the circle.
Therefore, the expression describing all the angles that are coterminal with 72° is:
θ = 72° + k * 360°.
