0.8888888 = 8/9
2.8888888 = 26/9
-2.888888 = -26/9
One way it's useful is in the application of phasors in physics. Phasors require you to add up vectors of two different angles, so the cosine angle addition formula can be used if you already know the cosine and sine of the original vector angles.
hi <3
area = length x width
substitute the values in:
7426 = length x 79
rearrange to get the answer:
length = 94 cm
hope this helps :)
Hello!
Let's change it to an equation.

Switch the equation around

First add 10 from 900


Divide both sides by 5
