<span>Triangle PQR is a right triangle. First we have to find the length of each side of the triangle. This can be done using the points provided, along with the Pythagorean theorem, which is a^2+b^2=c^2.
PR^2 = (7- -2)^2+(3-5)^2 = 85 => PR = sqrt(85)
QR^2 = (7- -1)^2+(3-1)^2 = 68 => QR = sqrt(68)
QP^2 = (1-5)^2+(-1 - -2)^2 =17 => QP = sqrt(17)
Now that we have the sides of the triangle, we can put them into the Pythagorean theorem again to see that it works out:
(Sqrt(17))^2 + (sqrt(68))^2 = (sqrt(85))^2
17 + 68 = 85
85 = 85
Since the Pythagorean theorem works for right triangles, the triangle is indeed a right triangle.</span>
There are 12 months in a year.... so divide apr by 12....
So, 1/3 of something is 21.
1/3 of x is not the full x: we know that the x is 21 and even more. So, it must be bigger than 21, since it has 21 and something else (and since 21 is not negative): the solution MUST be greater than 21.
Answer:
For example, 0.4 is less than 0.7. Let us now compare 1.57 and 1.6.
