Let's find the derivative of that hyperbola in order to find a slope formula to help us with this equation. We already have an x and y value. The derivative is found this way:

so

. The derivative supplies us with the slope formula we need to write the equation. Sub in the x value of 3 to find what the slope is:

. So in our slope-intercept equation, x = 3, y = 1, and m = -1/3. Use these values to solve for b.

so b = 2. The equation, then, for the line tangent to that hyperbola at that given point is

Answer:
<u>93°</u>
Step-by-step explanation:
According to angle sum property, all the internal angles of a triangle add up to 180 degrees.
=> 37 + 50 + ? = 180
=> ? = 180 - 87
=> ? = <u>93°</u>
