Answer:
C) 
Step-by-step explanation:
Use the Angle Addition Postulate to figure this out:
165° = (x + 15)° + (9x)°
165° = (15 + 10x)°
- 15° - 15°
_____________
![\displaystyle \frac{150°}{10} = \frac{[10x]°}{10} \\ \\](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B150%C2%B0%7D%7B10%7D%20%3D%20%5Cfrac%7B%5B10x%5D%C2%B0%7D%7B10%7D%20%5C%5C%20%5C%5C)
[Plug this back into the modeled expression for the 
to get the angle measure of 30°];

Answer:
78.5 cm
Step-by-step explanation:
C=2 X pi X r
r= radius
then divide by 2 for a half circle
The first equation is $3 times 9 = $27 the next equation iis $1 times 2 = $1
So you do 9 transactions over $100 and 2 transactions of $100 or lower.
It’s going to be the area of the triangle on the side times the length, so 0.5 x 36 x 15 x 48 = 12960
