Answer:

$y^2=9^2+19^2-2(9)(19)cos(41)$

Step-by-step explanation

That is the one that is correct.

In the picture attached, the angle is in the middle of side C, so the ecuation should be,

$c^2=a^2+b^2-2(a)(c)cos()$

Answer:

Step-by-step explanation:

This is something you learn in Geometry. Gotta love Geometry and all of its hundreds of rules for triangles and circles and all that good stuff!!

The rule for similar figures is

ratio of perimeter (one-to-one)-->area (square the one-to-one)-->volume (cube the one-to-one).

We are given area. You CANNOT CUBE THE AREA MEASURES TO GET TO THE VOLUME!! You have to find the one-to-one first and then go forward from there.

If the area is the one-to-one squared, then

$\frac{\sqrt{9} }{\sqrt{4} }=\frac{3}{2}$

The one-to-one is 3:2. To get to the volume now, cube those one-to-one values:

$\frac{3^3}{2^3}=\frac{27}{8}$

The number of pages in the U.S. tax code exceeds the number of pages in the King James Bible by 18,528. The combined number of p

LenaWriter [7]

Make two equations. Then solve. Let t and b represent the numbers of pages in the Tax Code and Bible, respectively.
t - b = 18,528 . . . . . tax code exceeds Bible by 18,528 pages
t + b = 21,472 . . . . .together, they total 21,472 pages

Add the two equations.
2t = 40,000
t = 20,000

The number of pages in the tax code is 20,000.
