Combine equations (9.1) and (9.2) in order to solve for e/m in terms of V (the voltage that accelerates the electrons), B (the magnetic field produced by the Helmholtz coils) and r (the radius of the circular electron beam). Hint: the first iteration of this calculation usually ends up with functions of e/m on both sides. To achieve the final result, e/m = some function of V, B and r, you'll need to do some algebra.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
