AB||CD. Find the measure of

140 degrees

Step-by-step explanation:

According to the adjacent angle theorem, 4x + 20 = 5x - 10 so x = 30. If x = 30, angle BEF is 140

Please give me Brainliest! (If I'm correct)

C) 140

Step-by-step explanation:

First find x by setting your formula up as

4x+20=5x-10

4x+20+10=5x

30=x

Now substitute 30 in place of x

5*30-10

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
