For the following question, assume that lines that appear to be tangent are tangent. Point O is the center of the circle. Find the value of x. ∡O = 142° (1 point) Responses 38 38 58 58 44 44 218
1 answer
The value of x would be 218 degrees, since the angle at the center of the circle is twice the angle at the circumference formed by the same arc. So, x = 2 * 142 = 284, and since the angle sum of a quadrilateral is 360 degrees, x = 360 - 284 = 76 degrees.
