Answer:
x = 50°
2x = 100°
Step-by-step explanation:
Chords AB and DC are equidistant (3 units) from the center E of the circle.
Since, the chords equidistant from the center of the circle are congruent.
Congruent chords intercepts congruent arcs.
Hence, x = 50°
2x = 2*50° = 100°
Answer:
x = 7
Step-by-step explanation:
I used the formula c^2 = a^2 + b^2
if you need further explanation,let me know
For this case, we have that by definition, the circumference of a circle is given by:

Where:
d: Is the diameter of the circle given by 2r, that is, twice the radius.
If we have a circle with a diameter equal to 8cm, then the circumference is given by:

Option C

Answer A is correct because the straight line is called a parallel line
