Answer:
P = 1.44 Watts
Step-by-step explanation:
We know that the relation between voltage and current in a simple circuit with a resistor is
V = I.R
Where
V = the voltage of the source
I = current of the circuit
R = resistance
The power is defined as
P = V.I
Which is the same as
P = V.(V/R)
P = (24 v)^2 / (400 ohm)
P = 1.44 Watts
tan = opposite/hypotenyse
for B, this is 24/25
24/25 = 0.96
Answer:
23°
Step-by-step explanation:
A complementary angle is 90°, so you can do 90°-67° =23°
