Answer:
a) m arc AD = 145
b) D = 10
Step-by-step explanation:
a) mAD can be found because triangle OCM can be shown to be congruent to triangle ODM.
The angle AOD is supplementary to DOB which we just showed to be congruent to the known 35° angle COB. Therefore AOD = 180 - 35 = 145°
The arc length is identical to the arc angle when measured between radii.
b) The radius OC = √(OM² + (CD/2)² = √(3² + 4²) = 5.
Diameter is twice radius = 10
Answer:
Arc length s = 15.3 inches
Step-by-step explanation:
We know that length of an arc that subtends an angle θ radians at the center is given by

where
r is the radius of the circle
θ is the angle subtended in radians
Thus applying values we get 
thus s = 15.3 inches
The answer is going to be 5f + 2e <span> hopes this helps :)

Answer: 10%
Step-by-step explanation:
even tho 100 is a bigger number the amount of 10% is 10 times bigger than 100%
