To find the missing value in the first question, where tan() = 38, you need to use the inverse tangent function (arctan) to find the angle. In this case, the angle can be found by taking the arctan of 38.
Using a scientific calculator or a built-in calculator on your computer or phone, input "arctan(38)" or "atan(38)". The result will be the angle in radians.
To convert the angle from radians to degrees, multiply the result by 180/π. This will give you the angle in degrees.
Once you have the angle, you can identify the corresponding value from the given options. In this case, the correct answer would be 44.25m, which matches the calculated angle.
Now, moving on to the second question, where sin() = 8/32. To find the angle, you need to use the inverse sine function (arcsin) to find the angle whose sine is 8/32.
Using a scientific calculator or a built-in calculator, input "arcsin(8/32)" or "asin(8/32)". The result will be the angle in radians.
To convert the angle from radians to degrees, multiply the result by 180/π. This will give you the angle in degrees.
Once you have the angle, you can identify the corresponding value from the given options. In this case, the correct answer would be 14.48m, which matches the calculated angle.
first off, trig functions are just numbers. they have no units (such as meters). Maybe those little m's are meant to be ° symbols.
If sin(x) = 8/32, x = 14.48°
