Evaluate the trigonometric expression using sum and difference formulas.
Basically, the question is asking, what will happen if we increase 9 by 30%?
first, what is 30% of 9?
So, the increase will be by 2.7 days,
So the total amount will be 9+2.7=11.7 - this is the correct answer.
The triangle lengths would be 14√2, 7√2 and 7√6.
The sides of a 45-45-90 triangle can be listed as t, t and t√2. The legs are each 14, so the hypotenuse will be 14√2.
This will also be the longest side of the 30-60-90 triangle. Its sides can be listed as t, 2t and t√3. Since the hypotenuse is the longest side, we have:
2t=14√2
Dividing both sides by 2, we have:
2t/2 = 14√2/2
t = 7√2
The remaining side will be t√3:
t = 7√2
t√3 = 7√2(√3) = 7√6
The answer is 34<span> because all you do is go from the radius to the diameter.
