If one angle of a triangle is 63 and the other two are 7x degrees and 6x degrees what is X worth
Black_prince [1.1K]

Answer:

    x = 9

Step-by-step explanation:

Sum of all angles of a triangle = 180

                63 + 7x + 6x  = 180

                  63  +  13x    =180

                             13x   = 180 - 63

                              13x  = 117

                                 x  = 117/13

x = 9
