Question:
Lines CD and DE are tangent to circle A, as shown below:
Lines CD and DE are tangent to circle A and intersect at point D. Arc CE measures 110 degrees. Point B lies on circle A.
If arc CE is 110°, what is the measure of ∠CDE
Answer:
70°
Step by step explanation:
The sum of two opposite angles in a Cyclic Quadilateral is 180°
Answer:
0 < x < 8
Step-by-step explanation:
| x-4| < 4
There are two solutions one positive and one negative. Remember to flip the inequality on the negative solution
x-4 <4 and x-4 > -4
Add 4 to each side
x -4+4 <4+4 and x-4+4 > -4+4
x < 8 and x > 0
0 < x < 8
open circles at 0 and 8 and a line connecting them
