Alex drew a circle with right triangle prq inscribed in it, as shown below: the figure shows a circle with points p, q, and r on it forming an inscribed triangle. side pq is a chord through the center and angle r is a right angle. arc qr measures 80 degrees.

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

Aline has a slope of and a y-intercept of –2. what is the x-intercept of the line?
