Since each angle of the hexagon is a 30 degree rotation just count the letters as you move and multiply by 30. 1. 120 degrees 2. 30 degrees 3. 30 degrees
Let the solutions be a and b. a = -2; b = -10 a + b = -2 + (-10) = -12 ab = (-2)(-10) = 20 (x - a)(x - b) = 0 (x - (-2))(x - (-10)) = 0 (x + 2)(x + 10) = 0 x^2 + 10x + 2x + 20 = 0 x^2 + 12x + 20 = 0 -h = 12 h = -12 4k = 20 k = 5
Answer:
cos60°
Step-by-step explanation:
Using the cofunction identity
cos(90 - x) = sinx , then
sin30° = cos(90 - 30)° = cos60°
