Answer:
C.
Step-by-step explanation:
Hope I could help :)))
Answer:
sin (a+b)= sina*cosb - sinb*cosa
cos (a+b) = cosa*cosb + sina*sinb
Use the sin function to solve for the central angle.
Chord length = 2Rsin(c/2)
where
chord length =4.5 feet
radius = 5 feet
C= central angle
Rearrange the formula to get the central angle and substitute all the given values
Central angle = 53.49 degrees
