Step-by-step explanation:
Statements
1.OD=OC OB=OA
2. measure of DOB equal m COA
3.Triangle DOB is congruent to triangle COA
4.BD equal CA
Reasons
1.radii of same circle is equal
2. Vertical angles are equal
3.SAS
4.CPCTC
$50+$10 (The coupon)=$60 to spend
$60/12=5 uniform shirts.
There are 180 Degrees in a triangle, you know two, 90 and 79, so the last angle is 11
180-90-79=11
If e-the initial hight of the tree, and the function imply some brackets like
f(x)=30/(1+29e-0.5x) then
for every

the rate of growth is negative, the maximum growth per unit of time would be 30ft
If

then

so the tree couldn't be 2ft tall initially
if the brackets are something like
f(x)=30:(1+29e)-0.5x then the results may differ
I am currently taking Geometry right now, so I understand where you are coming from. I think it's just a matter of approaching it differently. My teacher always says she is trying to get us to think, not memorize. If you think a tutor would help you, then go for it! Just make sure you are learning the material not just for the grade, but so that you actually understand it. That's the most important part. Good luck!
