Question

Hitunglah panjang sisi sisi berikut
a. PQ
b. RS​

Answer 1

Jawaban:

Penyelesaian :

• PS = 8 cm
• QS = 10 cm
• QR = 15 cm

Panjang sisi PQ

PQ² = QS² - PS²

PQ² = 10² - 8²

PQ² = 100 - 64

PQ² = 36

PQ = √36

PQ = 6 cm

Panjang sisi RS

RS² = QR² + QS²

RS² = 15² + 10²

RS² = 225 + 100

RS² = 325

RS = √325

RS = √25 × 13

RS = √25 × √13

RS = 5√13 cm
