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°

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
