in equilateral △abc, y =

a. 90°

b. 70°

c. 60°

d. 45°

B. 70°

Step-by-step explanation:

If this is an equilateral triangle, then each angle is   180/3 = 60

<A = 60 = x+3x+2x

      60 = 6x

     60/6 = 6x/6

  10 =x

Angle B will also equal 60 degrees

BDA  + x + B = 180

BDA + 10 + 60 = 180

BDA + 70 = 180

BDA = 180-70

BDA = 110

BDA  and y are complementary angles since they form a straight line

BDA + y = 180

110 +y =1 80

y = 180-110

y = 70

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

step-by-step explanation:

divide 900 by 2 to find 50% or half of 900

900/2=450

add 450 to 900
