Question

Adjacent angles of a parallelogram are( 5 x-213)° and (3 x-19)°. Find all the angles of the parallelogram

Answer 1

Answer:

1st and 3rd angle = 44 . 5

2nd and 4th angle = 135.5

Step-by-step explanation:

let  w, x , y , z ,are the angles of parallelogram

therefore  w = y and x = z

          so , w + x + y + z = 360

                  5x -213 + 3x - 19 + 5x -213 + 3x - 19 = 360

                    16x  =  824

                     x = 51.5

therefore, w = y = 5x - 213 = 44.5

                   x = z = 3x -19  = 135.5
