The consistency of repeated measurement, often expressed by the number of decimal places, is called a measurement's precision.
Answer:
2826 inches^2
Step-by-step explanation:
The general formula for the total surface area of a regular pyramid is
T.S.A.=12pl+B
Where p represents the perimeter of the base, l the slant height and B the area of the base.
The perimeter of the base is.
p=2L+2W
P=2*10+2*9
P=20+18
P= 38 inches
The area of the base is.
B=10*9
B=90in^2
T.S.A.=12(38)(6)+90
T.S.A=2736+90
T.S.A=2826 inches^2
Hence the paper needed is 2826 inches^2
Here, Angles under a straight line would be equal to 180
So, 70 + 60 + y = 180
130 + y = 180
y = 180 - 130
y = 50
Now, x = y [ As they are vertically opposite angles ]
In short, Your Answer would be 50
Hope this helps!
