The area of this figure is 10
Answer:
Please read the explanation to clarify.
Step-by-step explanation:
What you would have to do is multiply 1.06 by 4 to get 4.24. However, if you search up the exact conversion on g00gle, "how many liters are in 4 quarts?", you get the exact number of 3.78541, which can be rounded to 3.78. I believe if this is more of an exam thing, you should go with the first answer I gave, 4.24, and show how you multiplied to show your work. However, if you would like to use the second answer, it is completely up to you. Either way, I hope this helped, and if you have any further questions please don't hesitate to let me know. :)
Step-by-step answer:
Referring to the attached diagram, the resultant of two forces each with magnitude F and inclined to each other at 2a equals
Ra = 2Fcos(a) ..............................(1)
Similarly, the resultant of two forces each with magnitude F and inclined to each other at 2b equals
Rb = 2Fcos(b)..............................(2)
We are given that
Ra = 2Rb ....................................(3)
Substitute (1) & (2) in (3) gives
2Fcos(a) = 2(2Fcos(b))
Expand
2Fcos(a) = 4Fcos(b)
Simplify
cos(a) = 2 cos(b) QED

Have a nice day!
If the signs are alike, and ur adding/subtracting......u add them and keep the same sign
