Answer:
A
Step-by-step explanation:
∠QSR = 180° - 150° = 30° ( straight angle )
tanQSR = tan30° =
=
→ A
Answer:
C.) 60 feet
Step-by-step explanation:
Knowing that the formula for finding the circumference of a circle is
or
, we are able to set up the equation to be:
![188.4=3.14d](https://tex.z-dn.net/?f=188.4%3D3.14d)
![\frac{188.4}{3.14} =d](https://tex.z-dn.net/?f=%5Cfrac%7B188.4%7D%7B3.14%7D%20%3Dd)
![60=d](https://tex.z-dn.net/?f=60%3Dd)
and done! :)
Answer:
its c for sure, its obvious
Answer:
![6 \sqrt{3}](https://tex.z-dn.net/?f=%206%20%5Csqrt%7B3%7D%20)
Step-by-step explanation:
You need to factor out the greatest perfect square factor possible.
![\sqrt{75} + \sqrt{3} =](https://tex.z-dn.net/?f=%20%5Csqrt%7B75%7D%20%2B%20%5Csqrt%7B3%7D%20%3D%20)
![= \sqrt{25 \times 3} + \sqrt{3}](https://tex.z-dn.net/?f=%20%3D%20%5Csqrt%7B25%20%5Ctimes%203%7D%20%2B%20%5Csqrt%7B3%7D%20)
![= \sqrt{25} \times \sqrt{3} + \sqrt{3}](https://tex.z-dn.net/?f=%20%3D%20%5Csqrt%7B25%7D%20%5Ctimes%20%5Csqrt%7B3%7D%20%2B%20%5Csqrt%7B3%7D%20)
![= 5 \sqrt{3} + \sqrt{3}](https://tex.z-dn.net/?f=%20%3D%205%20%5Csqrt%7B3%7D%20%2B%20%5Csqrt%7B3%7D%20)
![= 6 \sqrt{3}](https://tex.z-dn.net/?f=%20%3D%206%20%5Csqrt%7B3%7D%20)
It is -27 because a negative number times a positive number is negative. In this case it is -9 times (3) which is -27.
