Answer:
°
Step-by-step explanation:
1. Approach
In order to solve this problem, one must first find a relationship between arc (a) and arc (c). This can be done using the congruent arcs cut congruent segments theorem. After doing so, one can then use the secants interior angle to find the precise measurement of arc (a).
2. Arc (a) and arc (c)
A secant is a line or line segment that intersects a circle in two places. The congruent segments cut congruent arcs theorem states that when two secants are congruent, meaning the part of the secant that is within the circle is congruent to another part of a secant that is within that same circle, the arcs surrounding the congruent secants are congruent. Applying this theorem to the given situation, one can state the following:

3. Finding the degree measure of arc (a),
The secants interior angle theorem states that when two secants intersect inside of a circle, the measure of any of the angles formed is equal to half of the sum of the arcs surrounding the angles. One can apply this here by stating the following:

Substitute,


Simplify,



<span>The mean would typically be the best measure of determining the success of this business. Barring the presence of any outlier values, finding the average number of cameras sold per period (week, month, year, etc.) would give a better picture than the range or mode. The median could be used, but it is a bit less descriptive than the median in this instance.</span>
Answer:
ok what teacher gave you this
Step-by-step explanation:
The temperature will be 84 degrees in 12 hours
The first factor must be at least 1 and less than 10.
The second factor must be a power of 10.
Move the decimal point to the left until the number is between 1 and 10. Count how many places you move the decimal point.23.6 → 2.36
You moved the decimal point 1 place to the left. The power of 10 is 10 to the power of 1
23.6 = 2.36 × 10 to the power of 1
