Step-by-step explanation:

by \: 30 \degree - 60 \degree - 90 \degree \: theorem \\  \\ 6 =  \frac{1}{2} b\\  \\ 6 \times 2 = b \\  \\ 12 = b \\  \\ \huge\red {\boxed {b= 12}} \\  \\ a =  \frac{ \sqrt{3} }{2} b \\  \\ a =  \frac{ \sqrt{3} }{2}  \times 12 \\  \\ \huge\purple {\boxed {a = 6 \sqrt{3}}} \\  \\ c =  \frac{1}{ \sqrt{2} } b \\  \\ c =  \frac{1}{ \sqrt{2} }  \times 12 \\  \\ c =  \frac{ \sqrt{2} }{2}  \times 12 \\  \\ \huge\orange {\boxed {c = 6 \sqrt{2}}} \\  \\

What is lim x→-3 sqrt x^2-8
vitfil [10]

If the  -8 is under the square root, then...

\displaystyle L = \lim_{x\to -3} \sqrt{x^2-8}\\\\L = \sqrt{(-3)^2-8}\\\\L = \sqrt{9-8}\\\\L = \sqrt{1}\\\\L = 1\\\\

OR

If the -8 is not under the square root, then...

\displaystyle L = \lim_{x\to -3} \sqrt{x^2}-8\\\\L = \sqrt{(-3)^2}-8\\\\L = \sqrt{9}-8\\\\L = 3-8\\\\L = -5

Either way, we replace x with -3 and simplify.

For more information, refer to the direct substitution rule for limits.

What's the equation of the line perpendicular to y=-3/2x+4 through the point ( 2,-3)
Korvikt [17]
Because it's perpendicular, you know that they must have the same slope, -3/2. So, just factor that and the point into the slope-point form to get

y = -3/2x
