Use distance formula:-
distance = sqrt [ (x2 - x1)^2 + (y2 - y1)^2) ]
let (x1,y1) = (-3,1) and (x2,y2) = (-1,6) Plug these values in to formula.
Blue: = because the equal sign is stating that it’s the same.
1 pound = 16 ounces
multiply the amount of pounds you have by 16 (that's how many ounces is in a pound) your answer should be whatever you get
example: you have 13 pounds, just multiply it by 16, the answer is 208.
so there are 208 ounces in 13 pounds.
or you could go google and ask them.
hope this helps.
So hmm notice the picture below
that's the 30-60-90 rule, notice your triangle, the bottom-left-angle is a right angle, 90°, the angle atop is 30°, so the angle on the bottom-right has to be 60°, thus is a 30-60-90 triangle, and as you can see on the triangle on the left in the picture, those are the ratios for it
so 8 will be x, what is the longer leg or side in yours then? well, is
