Please dijawab no.44 dengan cara penyelesaiannya!!!

d.10°
maaf kalau salah

< COD + < AOD = 180° ( sudut pelurus)
(2x + 10)° + (3x - 5)° = 180°
5x + 5 = 180
5x = 180 - 5
5x = 175
x = 175/5
x = 35
< COD = 2x + 10 = 2(35) + 10 = 80,
maka,
< BOC + < COD = 90° (sudut penyiku)
< BOC + 80 = 90°
< BOC = 90 - 80
< BOC = 10°
