T = √M² - A²
T = √3,9² - 1,5²
T = √15,21 - 2,25
T = √12,96
T = 3,6 cm
Ukuran tangga ( sisi )= 3,9 meter
Jarak kaki tangga → Dinding ( A ) = 1,5 meter
Tinggi dinding yang dicapai?
s² = a² + t²
(3,9)² = (1,5)² + t²
( 3,9 × 3,9 ) = (1,5 × 1,5) + t²
15,21 = 2,25 + t²
15,21 - 2,25 = t²
12,96 = t²
√12,96 = t
3,6 cm = t
t = 3,6 cm

• Diketahui :
Ukuran tangga ( sisi )= 3,9 meter
Jarak kaki tangga → Dinding ( A ) = 1,5 meter
• Ditanya :
Tinggi dinding yang dicapai?
• Jawab :
s² = a² + t²
(3,9)² = (1,5)² + t²
( 3,9 × 3,9 ) = (1,5 × 1,5) + t²
15,21 = 2,25 + t²
15,21 - 2,25 = t²
12,96 = t²
√12,96 = t
3,6 cm = t
t = 3,6 cm
