the cosine of 50 degrees is 0.64. what is the sine of 40 degrees?

Step-by-step explanation:

sin (90° - ∅) = Cosine ∅

40 = 90 - 50

sin (40°) = sin (90° - 50°) = Cosine 50° = 0.64

sin (40°) = 0.64

in 2010, the population of the state of california is 37.29 × 10⁶

step-by-step explanation:

population of los angeles = 3.79 × 10⁶

population of california = 9.84 × population of los angeles

                                        = 9.84 × 3.79 × 10⁶

                                        = 37.2936 × 10⁶

                                        = 37.29 × 10⁶

∴ in 2010, the population of the state of california is 37.29 × 10⁶
