Lines CD and DE are tangent to circle A, as shown below:
1 answer:
Using the outside angle theorem, the measure of angle CDE is: 70°.
<h3>How to Apply the Angle of Intersecting Tangents Theorem?</h3>According to the angle of intersecting tangents theorem, we would have the following equation using the diagram given:
Angle CDE = ½(measure of arc CBE - measure of arc CE)
Given the following:
- Measure of arc CE = 110°
- Measure of arc CBE = 360 - 110 = 250°
Plug in the values into the equation
Angle CDE = ½(250 - 110)
Angle CDE = 70°
