Please I need this answer I don’t understand

Step-by-step explanation:

by inspection

angles 2 and 3 are equal, so they will be half angle ABC

angles 1 and 5 are equal  so they will be

      angle 1 + angle 5 + angleABC = 180°      kind of a rule for triangle

                                                                        the sum of all angles - 180°

      (angle 1) x 2 = 180° - 70°

       angle 1 = 90° - 35°

      angle 1 = 55°   which equals angle 5

angle 4 is clearly a right angle 90°

DO the same procedure for the bottom triangle

angle 8 and 9 are half of angle ADC

angle 8 and 9 are half of 46°

both are 23°

angle 6 equals angle 7

2 ×angle 6 = 180° - 46°

angle 6 = 90° - 23°

angle 6 = 67°    angle 7 = 67°
