Solve for x by finding the missing side of the triangle. Round your answer to the nearest tenth. 20 Calculate the length of the diagonals using the distance formula, and determine if the quadrilateral with vertices A(-1,0), B(-3,5), C(2,7), and D(4,2) is a rectangle. It is a rectangle because both diagonals equal V58. It is a rectangle because both diagonals equal \\ 50. It is not a rectangle because one diagonal equals 158 and one equals \\50. It is not a rectangle because one diagonal equals 1 58 and one equals 7. Find the missing side lengths. Answers are in simplest radical form with the denominator rationalized. x =8, y=4 Ox = 16, y=4 Ox-4, y= 16 Ox = 8. y=4V/Z Identify the point of tangency in the circle shown
