Suppose sin (theta) =5/13 and pi/2 is less than or equal to theta, which is less than or equal to pi, identify the values of x, y, and r. Show work for finding the missing value, find the value of cos(theta), find the value of tan(theta). Thank you for your help

Lindsay used two points, (x, y; ) and (+2.82), to find the equation of the line, y = mx + b, that passes through the points. y2-y, first, she used the definition of slope and determined that the value of mis x, - . given this information, which expression must represent the value of b?

In the polynomial below, what number should replace the question mark to produce a difference of squares? x2 + ? x - 36
