Assume that lines that appear tangent are tangent. Point O is the center of the circle . find the value of x. Figures are not drawn to scale. M<o=145

OpenStudy (jessicawade):

the answers are 325 35 290 72.5 I think its 72.5

OpenStudy (anonymous):

x = 35 because every tangent makes a right angle (90 degrees) with the radius (line to O), the sum of angles in kite formed is 360 degrees 360 = x + 90+ 90 + 145 x = 180 - 145 = 35 degrees
