Question

What is the value of:
1 point
tan? 30° - 4 sin? 45°
A. 1
B. 7/3
C. - 5/3
D. - 11/3​

Answer 1

Step-by-step explanation:

Find these angles in degrees: (a) π/6; (b) 2π; (c) 1 (that’s right, radian angles aren’t necessarily fractions or multiples of π).

Solutions:

(a) (π/6) × (180°/π) = 30°

(b) 2π × (180°/π) = 360°

(c) 1 × (180°/π) = (180/π)° ≈ 57.3°
