Lines CD and CE are tangent to circle a. If m∠DAE = 145°, what is the measure of ∠DCE?

Tangent CD intersects with circle A at point D, tangent CE intersects with circle A at point E, angle ECD is on the exterior of circle A, and angle DAE has a vertex on the center of circle A.

35°
70°
145°
215°

  35°

Step-by-step explanation:

Angles DCE and DAE are supplementary, so ...

  ∠DCE = 180° -∠DAE = 180° -145°

  ∠DCE = 35°

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

it is c, trust i got your back lol
