12. In the given figure, ABCD is a parallelogram. Find x, y and z
Answers
Answer: x = 55 degrees
y = 124 degrees
z = 111 degrees
Step-by-step explanation: By extending DA to F we get AngleEAF = x as they are corresponding angles. So 125 - 180 = 55 which means angleEAF = 55 which says x = 55 degrees too... We know that ABCD is a parallelogram so angleDAB = angleBCD So angleY = 180 - 56 = 124 degrees... so ECB is a triangle. angleZ is an exterior angle of triangleECB. x = angleABC So angleABC = 55. So adding to interior angles of a triangle, we get an exterior angle. that is angleECB + angleCBE = angleZ. That is 56 + 55 = 111 degrees...
