Jawaban:
B. 46°
Penjelasan dengan langkah-langkah:
90°= 6x+4+5x+9
90= 11x+13
77= 11x
x= 77/11
x= 7
Penyiku BOC adalah AOC.
AOC= 6x+4
= 6(7)+4
= 42+4
= 46°
Besar sudut penyiku = 90°
(6x + 4) + (5x + 9) = 90
6x + 4 + 5x + 9 = 90
6x + 5x + 4 + 9 = 90
11x + 13 = 90
11x = 90 - 13
11x = 77
x = 77/11
x = 7°
Maka :
6x + 4
= 6(7) + 4
= 42 + 4
= 46 (B)
