58.3°
Step-by-step explanation:
Missing Information:
In this question the diagram is missing Following are the attachment of diagram of the given question.
As we seen that the vertex c is making the right angle i,e 90° also there is an acute angle the Hypotenuse: 20 cm and the perpendicular is 10.5 cm
Now we have find the best approximation of the angle ABC used the cosx trigonometric function.
Putting the value of perpendicular and hypotenuse in the previous formula we get
To calculate the standard deviation of those numbers:<span>
1
Work out the Mean (the simple average of the numbers)
2
Then for each number: subtract the Mean and square the result.
Then work out the mean of those squared differences.<span>Take the square root of that and we are done!</span></span>
