In quadrilateral pqrs, m∠rqs = 25° and ps = qr. what measure of ∠psq would confirm that pqrs is a parallelogram?

m∠psq = [ ]°

  25°

Step-by-step explanation:

If sides PS and QR are parallel, then ∠PSQ and ∠RQS are alternate interior angles, hence congruent. That is, ∠PSQ ≅ ∠RQS = 25°.

Comment on the problem statement

Confirming that two sides are parallel does not confirm the figure as a parallelogram. It could be a trapezoid. The given condition is necessary, but is not sufficient to do the confirmation.

a is the correct

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
