Answer
$85^{\circ}$
Work Step by Step
The reference angle of an angle $0 \leq \theta \lt 2\pi $ based on its position can be computed by using the following steps:
a) Quadrant- I: $\theta $
b) Quadrant -II: $(\pi-\theta)$
c) Quadrant- III: $(\theta - \pi)$
d) Quadrant - IV: $(2\pi - \theta)$
We are in quadrant 3, so subtract $180^{\circ}$:
Thus, the reference angle is $265^{\circ}- 180^{\circ}=85^{\circ}$
