The sin value = sin(arctan(7/-5)) = (-7/5)/sqrt(1 + (-7/5)^2) = (-7/5)/sqrt(1 + 49/25) = (-7/5)/(1/5)sqrt(25 + 49) = -7/sqrt(74) = -7sqrt(74) / 74
Therefore, the sine value of the function is <span>negative 7 square root 74 divided by 74</span>

Answer:
38.1 cm²
Step-by-step explanation:
area of full circle = π6² = 113.04 cm²
area of 150° segment = (150/360)(113.04) = 47.1 cm²
triangle base = sin 75° x 6 x 2 = 11.59
triangle height = cos 75° x 6 = 1.553
area of triangle = 1/2(11.59)(1.553) = 9 cm²
150° segment - triangle = 47.1 - 9 = 38.1 cm²
