Which of the following is the soultion: a. 45˚ b. 200˚ c. 240˚ d. 270˚ e.330˚

D. 270°

Step-by-step explanation:

The equation can be factored as ...

... (2sin(x) -1)(sin(x) +1) = 0

Then solutions are ...

... sin(x) = 1/2 . . . . x = 30°, 150° . . . . these values make the first factor 0

... sin(x) = -1 . . . . . x = 270° . . . . . . . this value makes the second factor 0

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
