Answer: find the answer in the explanation.
Step-by-step explanation:
In the circuit A;
The moment the switch S1 is opened, bulb A, B and C will go off simultaneously because they are all connected in series.
In the circuit B;
If S1 is opened, bulb G and H will both go off automatically while other bulb will still be functioning. The reason behind this is simply because G and H are in series and both bulbs are in parallel to the other bulbs.
Bulb F will follow by going off when switch S2 is opened.
Immediately switch S3 is opened, both bulb D and E will go off simultaneously because they are in series to each other.
Answer:
4.28
I think this it. I used a calculator online to help solve this problem. I don't know what the answer is but I used an online calculator to solve the problem. I rounded the answer to the nearest hundreth.
Answer:
5(2+8)+(12-6/3)2
5(10)+(12/1-6/3)2
50+(36/3-6/3)2
50+(30/3)2
50+60/3
50+20
70
Step-by-step explanation:
Finding x,
We will use Pythagoras theorem to determine the value of x:
Finding y,
We have to determine the angle, at the bottom left of the bigger triangle.
Using sine rule,
To find the angle on the smaller triangle,
Finding the missing length of y,
So y = 2 + 8, y = 10
