So, three sixty degree angles and three equal side lengths. A Doritos chip, perhaps?
Just do whatever legal moves it takes to make b be the only thing on one side of the equals sign. What is b in terms of everything else?
There are only 180 degrees in a triangle. What were those angles again?
sqrt 7 / sqrt 8 sqrt 7/ sqrt 4 times sqrt 2 sqrt 7 / 2 times sqrt 2 rationalize the denominator by mutliplying by sqrt 2/sqrt 2 and that is all.
This works, although it is a bit clunky. Find out what some convenient x values equal for y, such as 0, 1, and -1. Find out by visual inspection of a graph.
Are those 4's down low? Then they are bases. Whatever the log equals is an exponent. 4^2=2x 16=2x 8=x
base 10 you keep the base down low 10^2=2x The log is the exponent 100=2x 50=x
See above. I answered the most recent one first.
Imagine that you have a base of 10 down below and the just plain 2 is an exponent. 2x= 10^2 2x= 100 x=50
Just take 20, 38, and 62 times 0.112.
