tolong dibantu ya pake cara

24. A
Cari besar a nya dulu
2a + a = 180°
3a = 180°
a = 180°/ 3
a = 60°
Berarti 2a = 2 × 60° = 120°
27. C
Suplemen sudut 65° adalah :
180° - 65°
= 115°
Maaf tau nya cuma 2

24) 2a + a = 180°
3a = 180°
a = 180/3
a = 60°
Bssar sudut 2a = 2(60)
=120°

25) 2x-7+5x+12 = 180
5 + 7x = 180
7x = 180-5
7x = 175
x = 175/7
x = 25
Sudut terbedar adalah susdut 5x + 12
5x + 12 = 5(25) + 12 = 125 + 12 = 137'

26) p - 4 + 2p + 7 = 180
3p + 3 =180
3p = 180-3
3p = 177
p = 177/3 = 59

(p - 4) + a = 180
59-4 + a = 180
55 + a = 180
a = 180-55 = 125'
jadi bsar siudut a = 125'

27) Suplemen 65
x + 65 = 180
x = 180 - 65
x = 115

suplemen sudut 65 = x = 115'
