Can you please help me there is a picture there

A = 105

B = 60

C = 75

D = 120

Step-by-step explanation:

A opposite angle and parallel angle

B parralle angle and opposite angle

C all add up to 360 105 + 105= 210 and 360-210 = 150 divide by 2 = 75

D all add up to 360! (60 + 60 = 120 and 360-120 divide by 2 = 120

12cm

the answer is d

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
