Tolong d jawab no 6&7
thx

Answer 1

6. panjang PT = 5
mencari tinggi TQ2
= 144+25
=169
=13
luas = 1/2 x 5 x 13
=32,5 cm2

Answer 2

6.
PT = 5cm (15/3=5)
PQ = 12cm

mencari panjang QT :
akar 12kuadrat+5kuadrat= akar 144+25 = akar 169 = 13 cm
L PQT = 1/2 x a (pt) x t (qt) = 1/2 x 5 x 13 = 32,5cm

7.
RS=12cm
PQ=16,25cm = 16 1/4 cm
TQ=16cm

cari panjang pt dulu
PT=akar 16 1/4 kuadrat - 16kuadrat = akar 65/4 kuadrat + 16 kuadrat = akar 4225/16 + 256 = akar 4225/16 + 4096/16 = akar 8321/16= 91,2/4= 22,8

gak bisa nyelesaikan no. 7 bingung, maaf^^
