Answer:

$268yd^2$

Step-by-step explanation:

The Surface Area formula for a rectangular prism is:

$2(wl+hl+hw)$

where <em>w </em>is the width, <em>h</em> is the height, and <em>l </em>is the length.

Plug each value into the formula and solve:

$2(8*10+3*10+3*8)=268yd^2$

If this helped, a brainliest answer would be greatly appreciated!

Find sin3A, cos<br> 3A and tan 3A when sin=1/2<br>

Slav-nsk [51]

Answer:

Sin 3A = 1

cos 3A = 0

tan 3 A = undefined

Step-by-step explanation:

$\sin A = \frac{1}{2} \\ \therefore \: \sin A = \sin \: 30 \degree.. \bigg( \because \: \sin \: 30 \degree = \frac{1}{2} \bigg) \\ \therefore \: A = 30 \degree \\ \\ now \\ \sin 3A =\sin (3 \times 30 \degree)= \sin \: 90 \degree = 1 \\ \\ \cos 3A =\cos (3 \times 30 \degree)= \cos \: 90 \degree = 0\\\\ \tan 3A =\tan (3 \times 30 \degree)= \tan \: 90 \degree = \infty$
