the impedance Z, in ohms, of a circuit element is defined as the ratio of the phasor voltage V, in volts, across the element to
the phasor current I, in amperes, through the elements. That is, Z = V/I. If the voltage across the circuit element is 35+13i volts and the current through the element is 5-3i amperes, determine the impedance.

Answer:
For right angle triangle,
we use Pythagoras theorem that is:
c =
For question 1:
c = ?
a = 40
b = 9
putting them in formula,
c =
c = 41
For question 2:
c = ?
a = 12
b = 13
putting them in formula,
c =
c = approximately 17.69181
For question 3:
c = 35
a = 20
b = ?
putting them in formula,
1225 = 400 +
= 1225 - 400
= 825
b = 5
For question 4:
c = 37
a = 20
b = ?
putting them in formula,
1369 = 400 +
= 1369 - 400
= 969
Taking square root on both sides
b = 31.12
