Question

Pake caranya ya makasih :)

Answer 1

P. PS= 15 cm
P. PQ= 20 cm
P. SQ= ?

SQ²= PS² + PQ²
      = 15² + 20²
      = 225 + 400
 SQ= √625
      = 25 cm

P. SQ = P. SR= 25 cm

P. RQ= ?

RQ²= SQ² + SR²
      = 25² + 25²
      = 625 + 625
 RQ= √1.250
      = √625 . 2
      = 25√2

Jadi, panjang RQ adalah 25√2 cm (B).

Answer 2

dit = QR
QR = √SR² + SQ²
SR = SQ
SR/SQ = √PQ² + PS²
= √20² + 15²
= √400 + 225
= √625 = 25 CM
QR = √25² + 25²
= √625 + 625
= √1250
= 25√2 CM (B)
