Answer:
80°
Step-by-step explanation:
SPO+OPA+APC= 180°
(Angles on a straight line sum up to 180)
60+OPA+40=180
OPA=180-100
=80°
So, BPU is also 80°
(Vertically opposite angles are always equal)
Answer:
The voltage is 10 + 2j volts.
Step-by-step explanation:
Ohm's first law:
By Ohm's first law, the voltage is the multiplication of the current by the resistance, that is:

The voltage is measured in Volts, the current in amps and the resistance in ohms.
In this question:
Both the current and the resistance have complex parts. We have to know that:

We have that:

Then





The voltage is 10 + 2j volts.
