Answer: 
Step-by-step explanation:
For this exercise you need to use the Inverse Trigonometric function arcsine, which is defined as the inverse function of the sine.
Then, to find an angle α, this is:
In this case, you can identify that:
Then, substituting values into and evaluating, you get that the measure of the angle "C" to the nearest degree, is:
Because x is negative the domain of the function is all negative real numbers.
Set the radical greater than or equal to 0:
-x >= 0
Turn x positive by multiplying both sides by -1. When you multiply an inequality by -1 you need to reverse the inequality sign:
X <= 0
Domain is all real numbers below 0 so all negative real numbers.
Answer: x < 4
Step-by-step explanation: You are trying to isolate the variable, x, so you have to subtract 1 on both sides of the inequality. Then, you are left with x < 4.
Answer:
the number of short sleeves sold is 42
Step-by-step explanation:
The computation of the number of short sleeves sold is shown below:
Given that
The clothing store sold 98 long sleeve shirts
And, the ratio of short sleeve to long sleeve is 3:7
So, the number of short sleeves sold is
= 98 × 3 ÷ 7
= 42
Hence, the number of short sleeves sold is 42
