Answer:
Step-by-step explanation:
sin(90-a)=cos
cos = angle adjacent
theta=BC/CA
Answer: The central angle is 59 degrees.
Step-by-step explanation:
The sector or Arc Length is 59 degrees and the central angle is also 59 degrees, because the central angle equals the same measurement as the sector.
Answer:
Step-by-step explanation:
To get the other angles you need to do this
110+80+x+x=360
190+2x=360
2x=360-190
2x=170
X=170÷2
X=85
Equal to 5.13333...
Or 77/15
