Make use of the inverse sine function. Take the inverse sine of both sides of the equation. Of course, within the appropriate limits, the inverse sine of the sine function is the original argument, as is the case with any inverse function: f⁻¹(f(x)) = x.
... sin⁻¹(sin(x)) = sin⁻¹(-0.5)
... x = sin⁻¹(-0.5)
... x = -30°

You need to be careful with inverses of trig functions, because they are only defined over a limited domain and range. The range of the inverse sine function is -90° to 90°, so, for example, sin⁻¹(sin(150°)) = sin⁻¹(0.5) = 30°.
No, they're not equivalent
Answer:
$1875
Step-by-step explanation:
Given the information:
- An apartment costs: $625 per month
- They require that the cost of rent be no greater that a third of his monthly income
- The must earn at least 3 times the cost of his rent
=> the smallest amount of money that Carlos needs to make per month to be approved to move in:
= 3 times of $625
= 3*$625
= $1875
because 625 is exactly 1/3 of $1875
Hope it will find you well.
