Given:
AD is diameter of the circle, AB is the tangent, and measure of arc ADC is 228 degrees.
To find:
The 
and 
.
Solution:
AD is diameter of the circle. So, the measure of arc AD is 180 degrees.
The measure inscribed angle is half of the corresponding subtended arc.
AB is the tangent. So, 
because radius is perpendicular on the tangent and the point of tangency.
Therefore, 
and .

2. 
, the base is -1 and the exponent is 7
3. -2 * 
, the base is a and the exponent is 3
Answer:
- 15t + 5c = b
- $275
Step-by-step explanation:
Let "t' be the number of t-shirts bought.
Let "c" be the number of CDs bought.
Let b" be the total cost.
15t + 5c = b
We buy 10 t-shirts so t = 10.
We buy 25 CDs so c = 25.
We are trying to find b.
15t + 5c = b
15(10) + 5(25) = b
150 + 125 = b
275 = b
Best of Luck!
