substitute the value of 
in equ 1, we'll have
therefore, solution to the system of the equation is (1.5, 2.5)
the closest in your option is (1.4, 2.5)
AOD = 180 - (90+32) = 58 because when a tangent meets a radius they form a right angle
ABC = 1/2 AOD = 29 because it's subtended by the same ark as the AOD and O is center of the circle
