What is the solution to the equation below?
lara31 [8.8K]

Answer:

x=4096, Option B

Step-by-step explanation:

Given, \log_{8}x=4

Formula needed,

\log_{a}b=\frac{\log b}{\log a}

Therefore,

\log_{8}x=\frac{\log x}{\log 8}

\frac{\log x}{\log 8}=4

{\log x}=4{\log 8}

\log x={\log 8^4}

x=8^4

x=4096

Option B is correct.

If i have all the angles and one side can i find the other sides
harkovskaia [24]

Sure, that's what solving triangles is. Trigonometry has a short menu. Basically we choose between three formulas: Law of Sines, Law of Cosines, Sum of Triangle Angles

The Law of Sines has two sides and two opposite angles; given any three we can solve for the fourth.

The Law of Cosines has three sides and one angle; again given any three we solve for the remaining one.

The Sum of Triangle Angles says all three angles add to 180 degrees, so given two we can find the third.

Here we have all the angles and one side, that's Law of Sines to get the remaining sides.
