Question

if the angles of a quadrilateral are in bracket X + 10 degree X + 30 degree 2 x - 20 degree and 2 x - 38 degree find the angles of the quadrilateral

Answer 1

Answer:

Step-by-step explanation:

Sum of all the angles of a quadrilateral = 360

x + 10 +x +30 + 2x - 20 + 2x - 38 = 360

                                          6x - 18 =360

                                                 6x =360 +18

                                                    x = 378/6

                                                       =63

      1st angle = x +10 =73

      2nd angle = x + 30 = 93

      3rd angle = 2x - 38 = 88

      4th angle = 2x - 20 = 106
