The locus is the circle with its radius that size and its center at that point.
Its equation is (x+3)^2 + (y+1)^2 = 81.
Answer:
x = 17
Step-by-step explanation:
They are alternate exterior angles, so they are congruent. This means that:
True, because they're showing you the percentage.
Answer:
BE is 4 units long
Step-by-step explanation:
Data
Given that chords AC and BD intersect at E, then the following equation must be satisfied:
AE * CE = DE * BE
Replacing with data and isolating BE:
6*12 = 18*BE
BE = 6*12/18
BE = 4
