Answer:
Explanation:
So you want to start by finding the area of the big square.
We know the width to the big square is 60cm. The length to the big square is

Now let’s find the little square inside the bigger square. We see from the picture that the width is 34 and the length is 24cm. Using the same formula, we can find the area of the little square.
Little square

The area enclosed is the area of the big square minus the area of the little square.

So the area enclosed is

Answer:
6 hours 30 minutes
Step-by-step explanation:
morning work=3 hours 45 minutes
afternoon work=2 hours 45 minutes
total hours=?
Here,
3 hours 45 minutes+2 hours 45 minutes
=6 hours 30 minutes
Therefore,Terry Baelett worked 6hours 30 minutes a day.
Answer:
sin 5x cos x - cos 5x sin x = sin(4x)
Step-by-step explanation:
Given that the trigonometric expression,
sin 5x cos x - cos 5x sin x
Here we use the "sum and difference formulas"
Sum and Difference Formulas
sin(A+B)=sin A cos B + cos A sin B
sin(A-B)=sin A cos B - cos A sin B
cos(A+B)=cos A cos B - sin A sin B
cos(A-B)=cos A cos B + sin A sin B
So,
sin 5x cos x - cos 5x sin x = sin (5x - x)
sin 5x cos x - cos 5x sin x = sin(4x)
That's the final answer.
