It's a right triangle. Use the pythagorean theorem. 36^2+r^2=(r+12)^2. r=48.
Answer:
Option (3). 120° will be the answer.
Step-by-step explanation:
By using the theorem of secants intersecting externally,
Measure of angle formed by two secants, from a point outside the circle is half the difference of the measures of the intercepted arcs.
m∠C = 
36° = 
72° =
°
= 72 + 48
= 120°
Therefore, Option (3) is the answer.
1 2 4 8 16 32 64 128 256 512 1024. each one is 2 times the previous
5/8 = .625
531.25 / .625 = 850
850 - 531.25 = $318.75
