Lines CD and DE are tangent to circle A, as shown below: If arc CE is 110°, what is the measure of ∠CDE?
55°
70°
100°
125°

70º

Step-by-step explanation:

360º - 110º = 140º

then

140º /2 = 70º

or add up the 90º angles from the point of tangency to the circle

so 90º + 90º + 110º = 290º

so just subtract 290º from 360º

= 70º

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

its adding 5.5 each time
