Answer:
R = sqrt[(IWL)^2/(E^2 - I^2)] or R = -sqrt[(IWL)^2/(E^2 - I^2)]
Step-by-step explanation:
Squaring both sides of equation:
I^2 = (ER)^2/(R^2 + (WL)^2)
<=>(ER)^2 = (I^2)*(R^2 + (WL)^2)
<=>(ER)^2 - (IR)^2 = (IWL)^2
<=> R^2(E^2 - I^2) = (IWL)^2
<=> R^2 = (IWL)^2/(E^2 - I^2)
<=> R = sqrt[(IWL)^2/(E^2 - I^2)] or R = -sqrt[(IWL)^2/(E^2 - I^2)]

Answer:
.
Step-by-step explanation:

We need to find the factors of given equation;
Solution:
On Solving the above equation we get;
Now First we will take common factor from first 2 terms which is
we get;

Now we will take the common factor from the last 2 terms which is 3 we get;

Here we get 2 terms in which
is common factor.

Hence After factorizing the given equation we get
.
Answer:
the straight line will always equal 180 degrees.
180-125-35=20
the answer for the missing degree is 20
1.5 times 6 is equal to 9. So the answer is 9 kilometers
