Graphed in the standard (x, y) coordinate plane below is the line I and the circle with equation (x-2)2 +y2 = 1. Line i passes through (0,0) and is tangent to circle A and B is the center of the circle. What is the measure of AOB

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
