Question

which angle is coterminal with 135°? -225° -45° -155°

Explanation:

Step1: Recall the formula for coterminal angles

Coterminal angles can be found by the formula \(\theta\pm360^{\circ}n\), where \(n\) is an integer.

Step2: Check for \(n = 1\) (subtracting \(360^{\circ}\))

Let \(\theta=135^{\circ}\), then \(135^{\circ}- 360^{\circ}=-225^{\circ}\)

Answer:

\(-225^{\circ}\)
