The equilateral triangle has each angle equal to 60 degrees. So the small arc near x is also 60. The angle x is half the arc so would be 30. This also makes sense because the triangle it forms with angle x and the center has center angle of 60 and angle formed by tangent and radius of 90. So it is a 30-60-90 triangle, making angle x 30.
To find the answer to this question, we need to plug in x=10 into the equation y = -63x + 825. y = -63(10) + 825 y = -630 + 825 y = 195 Thus, there will be 195 cans left after 10 days.
