Answer:
Step-by-step explanation:
Assuming that arc AB is where the inscribed angle meets the outside of the circle, then the rule is that the inscribed angle is 1/2 of the measure of its intercepted arc. For us,

Solving for x:
2(5x - 7) = 2x so
10x - 14 = 2x and
8x = 14 so
x = 1.75
Answer:
C. Surveys
Step-by-step explanation:
A primary source of information is the gathering of data that hasn't already been collected.
One of the best ways is to use a market research survey.
A, B, and D are wrong. They are all secondary sources — they provide information that someone else has generated.
Step-by-step explanation:
1. 10-(2+3) = 5
2. 2x3 - 10 = -4
3. 3 x (4-2) = 6
4. (3+5) / 4 = 2
5. (5-2) x 3 = 9
6. (9-4) + 5 = 10
