# Chapter 1 - Trigonometric Functions - Section 1.1 Angles - 1.1 Exercises: 113

-61$^{\circ}$ in the IV quadrant

#### Work Step by Step

1. Coterminal angles always in the same quadrant with original angle, because of full resolutions (2π) -61° + 360° = 299° -61° - 360° = -421° 2. 270-360 degrees in the fourth quadrant. Therefore 270$^{\circ}$≤299$^{\circ}$≤360$^{\circ}$ its in the fourth quadrant
