Your expression equals $2 \sin(\frac{\pi}{4})$ assuming the problem was to simplify $2\sin(\frac{\pi}{8}) 2\cos(\frac{\pi}{8})$ to the form $a\sin(\theta)$ .

Step-by-step explanation:

$2\sin(\frac{\pi}{8}) 2\cos(\frac{\pi}{8})$

$2(2)\sin(\frac{\pi}{8})\cos(\frac{\pi}{8})$

Let's use the following identity: $2\sin(A)\cos(A)=\sin(2A)$

$2\sin(2 \cdot \frac{\pi}{8})$

$2 \sin(\frac{\pi}{4})$ which is comparable to the form $a\sin(\theta)$ .

$a=2$

$\theta=\frac{\pi}{4}$

Determine the volume of the square pyramid below h-4 b1-6 b2-6 144 square units 36 square units 72 cubic units 48 cubic units

bagirrra123 [75]

Answer:

V = 48 cubic units

Step-by-step explanation:

$V=b^{2} \frac{h}{3}$ Use this equation to find the volume

$V=6^{2} \frac{4}{3}$ Simplify the exponent

$V=36(\frac{4}{3})$ Multiply

V = 48 cubic units
