It is 30-60-90 triangle, so:
Answer B.
Answer:
D. 25%
Step-by-step explanation:
There are two ways that I do this. Both of them are probably not what your teacher tells you, but hey, I got the right answer.
The first method is to go through the answers and do 14 x .10, 14 x .20, and so on until you get 3.50.
The second method is to do 14/3.5, which equals 4. This means 14 can be broken up into 3.50 four times. So, 3.50 is 1/4 of 14. What is 1/4 of 100%? 25%.
I think 3 because if u divide 207 by 69 you get 3
In 4 seconds, number of beats = 28
In 1 sec., it is = 28/4 = 7
Now, In 30 seconds, it would be: 30 * 7 = 210
In short, Your Answer would be: 210 beats
Hope this helps!
Radius = 15 feet
circumference = 2 * PI * 15 =

94.25 </span></span></span>feet
the length of the arc is 10 feet
So the angle would equal (10 / 94.25) * 360 =
