50 i think that’s it sorry if it’s wrong
You have to be able to know the appropriate properties or postulates to apply on the angles or segments to simplify them. An example would be the Angle Addition Postulate. This postulates states that the sum of the individual measures of the interior angles is equal to the measure of the included angle. There are still a lot more properties to choose from depending on the situation.
The answer is 60 people. Each person would get <span>4 pins, 6 ornaments and 9 mugs.</span>
The equation of the tangent line is 
To find the tangent to the hyperbola
at (x₀, y₀), we differentiate the equation implicitly to find the equation of the tangent at (x₀, y₀).
So, 
So, at (x₀, y₀)

So, the equation of the tangent line is gotten from the standard equation of a line in point-slope form
So, 
So, the equation of the tangent line is
