if y is equal to 32 degree z equal to 40 degree find x if y + z is equal to 90 degree prove angle x is equal to 45 degree

ANGLE C = 90
ANGLE X = 45 AS ANGLE X + ANGLE C + ANGLE X = 180 [ANGLE SUM AND PROPERTY ]
                             :90 + 45 + X = 180
                           SO X = 180 - 90 +45= 180 - 135
                                        
                           SO ANGLE X = 45
