Question 1 • AZ-Common Core Algebra II B

Which of the following represents the measures of all angles coterminal with a 418° angle?

Answer
A
360 + 58n, for any whole number n
B
58 + 360n, for any integer n
C
58 + 360n, for any whole number n
D
360 + 58n, for any integer n

Explanation

Coterminal angles differ by whole rotations of 360°. Since 418° − 360° = 58°, all angles coterminal with 418° have the form 58 + 360n, where n can be any integer (positive, negative, or zero). This matches choice B.
