In which triangle is the value of x equal to cos−1(StartFraction 4.3 Over 6.7 EndFraction)? (Images may not be drawn to scale.)

A right triangle is shown. The length of the hypotenuse is 6.7 and the length of another side is 4.3. The angle between the 2 sides is x.

The first choice

Step-by-step explanation:

The pyramid volume formula is this:  bh(1/3)

the rectangular prism volume is this: bh

Looking at these formulas, we can see that the rectangular prism is three times the pyramid, so Shannon has to be correct.

Because rectangular prism is three times pyramid, the volume of the rectangular prism is 60*3 = 180

When we divide it by the height, we get the base area: 180/5 = 36

Therefore, the first choice is correct.
