Answer:
30°
Step-by-step explanation:
First we must know that the sum of the interior angles of a triangle sum up to 180°. Furthermore, a straight line is also 180°. By using these what we know we can determine what the value of m∠X is.
First we know that m∠W and m∠Z make up a straight line, since m∠W is 105° it follows that:
180° = m∠W + m∠Z
And so:
m∠Z = 180° - m∠W = 180°-105° = 75°
m∠Z = 75°
Now, we also know that the sum of m∠X + m∠Y + m∠Z = 180° and so:
m∠X = 180° - m∠Y - m∠Z
m∠X = 180° - 75° - 75° = 30°
Therefore, m∠X = 30°

Answer:
Reactive power is 1.152 VARs
Step-by-step explanation:
We are given that in a parallel circuit,
,R=47kΩ and 
=50kΩ.
reactive power means the dissipating power resulting from inductive and capacitive loads measured in volt-amperes reactive(VAR).Since our circuit has inductor only, reactive power will be power dissipated from inductor.
Current through inductor=
milli amps=0.0048 A
Reactive power = (current flowing through inductor)X (Voltage across inductor)
Hence reactive power = 0.0048 X 240=1.152 VARs
We can not really tell in this question as you dont know the equation that is being used for the domain and range relationship but overall one should know that:
The set of values of the independent variable(s) for which a function or relation is defined as the domain of a function. Typically, this is the set of x-values that give rise to real y-values.
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.
