Answer:
Step-by-step explanation:
Value of Sam's car after t years =
=
Value of Sam's car in 5 years=

= $ 4437
F = kq2 / r2
q = ne
F = k(ne)2 / r2
n = âš(r2F / ke2) = (r/e) âš(F/k)
k = 9 x 109 Nm2/C2
e = 1.6 x 10-19 C
n = [(4.2 x 10-10) / (1.6 x 10-19)] âš[(5.2 x 10-9) / (9 x 109)] ≅ 1.995 ≅ 2
70
this is because the bottom line has to equal 180, the angles given, 50 and 60, add up to 110, meaning the missing angle is 70 hope this helps :)
