Answer:

Below.

Step-by-step explanation:

In a right triangle:

sin x = opposite side / hypotenuse

cos x = adjacent side / hypotenuse

tan x = opposite side / adjacent side

In this triangle the hypotenuse = 12 and the adjacent side = h

so we use cos 47

cos 47 = h / 12

h = 12 cos 47

h = 8.2 cm.

Simplify completely.<br><br> (h^12h^4)^3

hichkok12 [17]

$(h^{12}h^4)^3$
You need to work inside out. $(h^{12}h^4)$ simplifies to $h^{16}$ .
Now you need to cube that. $(h^{16})^3 = h^{48}$
Therefore the solution is $h^{48}$ .
