EF is tangent to the circle we'll assume; otherwise there's no progress.
Call the center C. ECD is isosceles, formed from two radii and the chord.
Angle CED is complementary to DEF
CED = 90 - 65 = 25 degrees
CDE is congruent, isosceles triangle and all that: CDE=25
That leaves DCE=180-25-25=130 degrees
That's the measure of arc DE as well:
Answer: 130 degrees, choice A
<span>14554345555556675566669878 is your answer.
All you have to do when adding 1 is add the number at the very end of the number +1.
It's quite easy.
Glad I could help, and good luck!

Answer:
- b. 25.7 + 13.2 + 6.4 = 45.3
Step-by-step explanation:
25.65 ≈ 25.7, 13.23 ≈ 13.2, 6.35 ≈ 6.4
- 25.65 + 13.23 + 6.35 =
- 25.7 + 13.2 + 6.4 =
- 45.3
Correct choice is b.
