Their is a 18 degree difference
The sine ratio that was applied in step 2 is incorrect, therefore, the first error is in: B. step 2.
<h3>How to Apply the Sine Ratio?</h3>
The sine ratio that is applied when we want to solve a right triangle is, sin ∅ = opposite length / hypotenuse length.
In step 2, the sine ratio applied is wrong because:
- ∅ = W
- Opposite length = XZ
- Hypotenuse length = y
Thus, we should have:
sin(W) = XZ/y
The first error is in: B. step 2.

Step-by-step explanation:
We can multiply all of the roots and all of the whole numbers together in this fashion:
this simplifies to:
45 * 6
= 270
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:

Simplify,
