There is of course no one true answer, but an infinite number of them, all correct. Let's go with
Answer: 7.7 + π/100
Pi divided by 100 is .031415926.... so this is about 7.73141526.
Another answer, perhaps looking more like what you'd call a number, is the square root of 61, about 7.81.
Answer: √61
Answer:
It's either 35 x10^(-13) or 3.5 x10^(-13)
Step-by-step explanation:
35 x 10^(-13) = 3•5 x 10 x 10^(-13)
3•5 x 10 x 10^(-13) = 3•5 x 10^(-12)
Hope I'm correct
Provided that the triangle looks like this:
A| \ | \ | \ | \ | \ b| \ 20 | \ | \ | \ | \ |_______40\C a B
Then using the the equation to solve for line segment AC (or b on the diagram):
sin(40) = b/20
b = 20 * sin 40
b = segment AC = 12.9 units
180 is the answer to the question
