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?

55°
70°
100°
125°

70 degress

Step-by-step explanation:

The specific theorem is that if an angle is formed by two tangents outside of the circle, then the measure of that angle is equal to the difference of the intercepted arcs (major arc and minor arc)

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
