The answer is -5 because a negative times a negative is a positive.
Using the given equation:
10PI/X = 240/360
Cross multiply:
(10PI*360) = (240*X)
3600PI = 240X
Divide both sides by 240:
X = 3600PI / 240
X = 15PI in^2
Step-by-step explanation:
If x=3, y=7 when x+y=z
z=3+7
z=10
D. 3
You can use Pythagorean Theorem to figure this out.
a^2 + b^2 = c^2
4 would your b, and 5 would be your c. You would then solve for a.
Also, 3-4-5 triangles are just something that you can always count on. If two sides of a triangle are 3 and 4, you can count on the hypotenuse being 5. On the other hand, if you know the hypotenuse is 5 and you know one of the other sides is either 3 or 4 (let’s say 3, for example) then you know the missing side has to be the other number (which would be 4 in the example i gave).
