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.
20/24-(-18/24)=38/24
Subtracting a negative is adding a positive.
20/24+18/38
38/24
24 goes into 38 once and 14/24 is left over.
1 14/24
Divide the fraction by two for simplest form.
1 7/12
Answer:
D) 45 ft
Step-by-step explanation:
The two triangles are shown below.
Given:
BC = 60 ft, CD = 24 ft and DE = 18 ft.
Since, the two triangles are similar, their corresponding sides are in proportion.
So, 
Now, consider the proportion of sides,

Therefore, the distance between A and B is 45 ft.
A triangle is 180 degrees. X+first length+second length=180. Then solve
The answer is 27 degrees i know i took the test
