Step-by-step explanation:
Draw the triangle formed by the ray.
The hypotenuse of the triangle is:
c² = a² + b²
c² = (-5)² + (2√7)²
c² = 25 + 28
c = √53
Therefore:
cos β = -5 / √53
Or, as a proper fraction:
cos β = -5√53 / 53
Paul made $70 shoveling snow and $25 salting driveways. He set 35% of his total earnings aside for taxes. How much did he set aside for taxes?
