Step-by-step explanation:
For finding the polygon's area, we first need to find the length and the breadth/width, for finding the length, we need to see the difference in the plane of the two points, the first 2 points are
A and B,
A is at (-5,-2) and B is at (4,-2), Hence the change in the x coordinate is 9 so 9 is our length, Now for the breadth/width, the coordinates are of C and B
C is at (4,-7) and B is at (4,-2), the difference in the y coordinate is 5, hence the width is 5, the reason why the breadth is taken as from C and B and not from C and D is because the last endpoint of the length is to be taken.
Hence,
A = L * B
=> A = 9 * 5
=> A = 45 units

7(4x+4)+5x, 28x+28+5x, 33x+28. Answer: A.
Answer:61.3
Step-by-step explanation:
Using the Law of Sines, you get this formula
sin(angleA)=(a*sin(angleB))/b
sin(angleA)=(14*sin(70)/15)
sin(angleA)=(.88)
angleA=sin-1(.88)
angleA=61.3
You must divide mass of carbon by mass of carbon atom.
There are 3 zetta atoms of carbon in 6g of carbon.
Hope this helps.
Answer:
Both X and Y are equal to 15 multiply by the square root of 2.....(i just do not know how to type the symbol on my keyboard)
Step-by-step explanation:
So for X:
X=30 sin 45
=15 multiply by the square root of 2
For Y:
Y=30 cos 45
=15 multiply by the square root of 2
But you could also use theorem of Pythagoras
