Tolong dijawab donk nomor 5 sama 6

spq = 8p-4
qrs = 3p + 7
rsq = 6p + 4
rsq = rqs
rsq+rqs+qrs = 180
6p+4+6p+4+3p+7 = 180
15p+15 = 180
15p = 180 - 15
15p = 165
p = 11

spq = 8p-4
spq = (8 . 11) - 4
spq = 84

pqs = psq
spq + 2(pqs) = 180
84 + 2(pqs) = 180
2(pqs) = 180-84
2(pqs) = 96
pqs = 96 : 2
pqs = 48 (C)
