Consider the figure below. Abraham cut regular pentagon ABCDE into quadrilateral BEGC. Which of the following statements is true about quadrilateral BEGC? (picture included)

Correct: 2, 3, 4, 6

Step-by-step explanation:

ABCDE is a regular pentagon. The sum of the measures of all interior angles in the pentagon is

then the measure of each interior angles in the regular pentegon is

Triangle ABe is isosceles triangle, so the adjacent to the bas BE angle has the measure

Therefore,

(option 2 is correct)

Since then

The sum of the measures of all interior angles in quadrilateral BCGE is

(option 6 is correct), then

(option 1 is false)

(option 3 is correct)

(option 4 is correct)

(option 5 is false)

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
