5) < EAB = < EBC
2x+3 = y+17
2x-y=17-3
2x-y=14 ( pers 1 )
< EAB + < EBC = 90°
2x+3+y+17=90
2x+y=90-3-17
2x+y=70 (pers 2)

2x-y=14
2x+y=70 (+) (eliminasi)
_______
4x = 84
x = 84/4
x = 21

2x-y=14
2×21-y=14
y=42-14
y=28
Nilai dari y - x = 28 - 21 = 7 (B)
6) < E + < F = 180°
2x+13+3x+2=180
5x+15=180
5x=180-15
5x=165
x=165/5
x=33
jadi < E = 2x+13
= 2×33 + 13
= 66 + 13
= 79° (A)
7) x=108°
y= 1/2×96°=48°
Nilai x - y = 108° - 48° = 60° (C)
