kaka tolongin ka gmna cara No 23 sama 24 nya ka? nih sma aku udh tmbahin poin nya!

23. sudut ABG = sudut FDE
3x - 48 = x + 22
2x = 70, x = 35
Sudut ABG = 3x - 48 = 3 (35) - 48 = 57

sudut ABG + sudut BCF = 180
57 + sudut BCF =180
sudut BCF = 123

24. sudut segitiga = 180

sudut ACB + sudut BAC + sudut ABC = 180
(180-100) + 48 + (180-(2x-16) = 180
80 + 48 + 180 - 2x + 16 = 180
128 - 2x + 16 = 0
144 = 2x
x =72

23. y+3x-48°=y+x+22°
2x =70°
x =35°
fcg = cde
= x + 22°
= 35° + 22°
= 57°
bcf = 180° - fcg
= 180° - 57°
= 123° (A)

24. < abc = 52°
< dba = < dbc + < abc
180° = 2x - 16° + 52°
2x = 144°
x = 72° (D)
