Tolong bantu aku dong,,,please!!!!.BESOK MAU DIKUMPUL BESOK

[tex](6x + 4) + (5x + 9) = 90 \\ 6x + 5x + 4 + 9 = 90 \\ 11x + 13 = 90 \\ 11x = 90 - 13 \\ x = 77 \div 11 \\ x = 7[/tex]
x = 7
sudut BOC 5x+9 = 5×7+9
= 44°

[tex](a + 3) + 2a = 180 \\ 2a + a + 3 = 180 \\ 3a = 180 - 3 \\ a = 177 \div 3 \\ a= 59[/tex]
a = 59
Sudut AOC = a + 3
= 59+3
= 62°


semoga benar...
