tolong bgt ya no. 2 sama 3

2.
a.
PR² = PS x PQ
12² = 6 x PQ
144 = 6 PQ
PQ = 144 / 6
PQ = 24 cm

b.
RS² = PS x SQ
RS² = 6 x (24 - 6)
RS² = 6 x 18
RS² = 108
RS = √108
RS = √(36 x 3)
RS = √36 x √3
RS = 6√3 cm

3.
a.
NL² = KL² - KN²
NL² = 10² - 6²
NL² = 100 - 36
NL² = 64
NL = √64
NL = 8 cm

b.
KL² = NL x ML
10² = 8 x ML
100 = 8.ML
ML = 100 / 8
ML = 12,5 cm
