Answer:

AB = 8.39 inches

AC = 13.1 inches

(corrected to 3 significant figures.)

Step-by-step explanation:

In a right triangle, AB is the opposite side; BC is the adjacent side, and AC is the hypotenuse side.

since tanθ = opposite / adjacent,

we can use this to find side AB.

tan40° = AB / 10

AB = 8.39 in. (corrected to 3 significant figures.)

since cosθ = adjacent / hypotenuse

we can use this to find AC.

cos40° = 10 / AC

AC = 13.1 in. (corrected to 3 significant figures.)

I have 15a but I need 15b and 14
Naily [24]
14. For a prism, the volume is given by
.. V = Bh . . . . . . . . where B is the area of the base, and h is the height of the prism

For a pyramid, the volume is given by
.. V = (1/3)*Bh . . . . where B is the area of the base, and h is the height of the pyramid

The volume is proportional to the area of the base. If the dimensions of the base decrease linearly to zero at the height of the geometry as they do for pyramids and cones, then the volume formula includes a factor of 1/3.


15b. The volume of a pyramid is 1/3 that of a prism with the same base area and height.
