Answer:
I believe the correct answer is A
Step-by-step explanation:
Answer: C
The formula for tangent is tan(x)= opposite/ adjacent so plugging it in would be tan(x)=9/4
Answer:
C = pi * d = 2 * pi *r
Step-by-step explanation:
The circumference of a circle is the distance around the circle. It can be found by multiplying the diameter times pi.
C = pi * d
We can replace the diameter with twice the radius
C = pi * 2 * r = 2 * pi *r
180 - 64 = 116
116 / 2 = 58 :)
Check: 58 + 58 + 64 = 180
