Question

The hypotenuse of a right triangle is 26 cm long. If one of the remaining two sides is 10 cm long, the length of the other side is
(a) 25 cm
(b) 23 cm
(c) 24 cm
(d) 22 cm

Answer 1

In right traingle BOC,
BC² = OC² + OB²
⇒ (26)² = (10)² + OB²
⇒ 676 = 100 + OB²
⇒ OB² = 576
⇒ OB² = (24)²
⇒ OB = 24 cm
Hence, the correct answer is option (c).
