Answer:

AC ≈ 5.3 ( to the nearest tenth )

Step-by-step explanation:

Using the cosine ratio in the right triangle.

cos68° = $\frac{adjacent}{hypotenuse}$ = $\frac{AB}{AC}$ = $\frac{2}{AC}$

Multiply both sides by AC

AC × cos68° = 2 ( divide both sides by cos68° )

AC = $\frac{2}{cos68}$ ≈ 5.3

Answer:

5.3

Step-by-step explanation:

Cos(68) = adjacent/hypotenuse

Cos(68) = 2/AC

AC = 2/cos(68)

AC = 5.3389343253

AC = 5.3

he volume of a square pyramid is 288 in^3in 3 and the square base has a perimeter of 48 inches, find the height of the pyramid.

drek231 [11]

Answer:

Perimeter = 4s

s = P/4

s = 48 in/4

s = 12 in

V = a^2h/3

h = 3V/a^2

h = 3(288 in^3)/ (12 in)^2

h = 864 in^3 / 144 in^2

h = 6 inches

How do I know that the following equation is true:

PSYCHO15rus [73]

Answer:

<u>Half angle Identity for cosine</u>:

$\cos \left(\frac{\theta}{2} \right)=\pm \sqrt{\frac{1+\cos(\theta)}{2} }$

$\text{Note that it is} \pm \text{because we don't know which Quadrant the half-angle is, }$ $\text{the information of}\cos(\theta) \text{is not enough to conclude the angle}$

$\frac{\pi}{8} \text{ is a Quadrant I angle, therefore, positive}$

$\cos \left(\frac{\pi}{8} \right)=\sqrt{\frac{1+\cos(\frac{\pi}{4} )}{2} }$

The equation is true.
