Answer:
Step-by-step explanation:
Remark
The solution to this is to add the two vertically opposite arcs and take 1/2 of the result to get the intersecting angle of the chords.
Solution
<x = 1/2 (arc measure of 116 + 74)
<x = 1/2 (190)
<x = 95
5.2 meters = about 17.06 feet (rounded)
Answer:
b. 
Step-by-step explanation:
Given expression is:

Let us factorize the numerator using the formula:


Since x ≠ 3, let us cancel the common factor x - 3 in the numerator and in the denominator.
So,

where (a,b) are the coordinates of the center and r , the radius.
For the given equation: a = 3 , b = -1 and r = 9
hence centre = (3 ,-1) and radius = 9
