Use a calculator to determine angle x, rounded to the nearest degree.
csc x = 1.25
To determine angle x, you can use a scientific calculator to find the inverse cosecant (csc⁻¹) of 1.25.
Here are the steps to follow:
1. Press the "Mode" button on the calculator.
2. Select "Degree" as the angle measurement mode.
3. Press the "2nd" or "INV" button on the calculator.
4. Find the csc⁻¹ or arcsin (sin⁻¹) function on the calculator. It may be labeled as "sin⁻¹" or "asin" depending on the brand and model of the calculator.
5. Enter 1.25.
6. Press the "=" or "Enter" button on the calculator to calculate the result.
The calculator will display the angle x in degrees. Round this value to the nearest degree as requested.
Note: Make sure to check that your calculator is set to the same mode (degrees) as your question asks for.
OK. Now what?
Hint: sin x = 1/1.25 = 0.8
