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
No 3/4 is NOT equal to 5/6

Answer:
Therefore the length of line Segment BC is 20.5 in.
Step-by-step explanation:
Given:
In Right Angle Triangle ABC
∠C = 90°
∠B = 35°
BC = a
AB = hypotenuse = 25

To Find:
BC = ?
Solution:
In Right Angle Triangle ABC , Using Cosine Identity we get

Substituting we get

Therefore the length of line Segment BC is 20.5 in.
