Answer:
108°
Step-by-step explanation:
Suppose that circle with center A is a circular arena. Points B, C, D, E and F are 5 lights. These 5 points form regular pentagon (because these 5 lights are equally spaced around the perimeter of the arena).
The sum of all interior angles of pentagon can be calculated using following formula
All interior angles in regular pentagon are of equal measure, so
Thus, the measure of each angle formed by the lights on the perimeter is 108°.
Answer:
-4x+4
Step-by-step explanation:
Answer:
Option B is the right choice,congruent to are .
Step-by-step explanation:
If we look on to the diagram and the options we can sort out the angles on the basis of our requirement.
There are three sets arising from the angles.
[Corresponding angles]
The corresponding angles are the ones at the same location at each intersection.
[Vertically opposite angles]
And
[Alternate interior angles]
Now
[Corresponding angles]
[Vertically opposite angles]
[Vertically opposite angles]
So the correct pair from the options given is B which includes
