Answer:
15/17
Step-by-step explanation:
cos(arctan(8/15)) = 15/17
__
You could assume the ratio values 8 and 15 represent the opposite and adjacent sides of a right triangle. Then the hypotenuse is ...
h = √(8² +15²) = √289 = 17
The cosine is the ratio of the adjacent side to the hypotenuse, so is ...
cos(x) = 15/17
Answer:
x= 0.4
Step-by-step explanation:
x^2 = 4/25 (0.16)
x = 0.4 Square root both sides
We want to add these together and then subtract from one. So to add them, find a common denominator.
The closest common denominator is 20.
So convert the fractions:
5/20 and 8/20
Then add
5/20 + 8/20 = 13/20
And then subtract from 1.
1 - 13/20 = 7/20
The third partner owns 7/20 of the company.
