The hypotenuse of a right triangle is 26 cm and one leg is 24 cm. The other leg is
A8 cm
B10 cm
C12 cm
D14 cm
Answer & Solution
Correct answer: B. 10 cm
1. By Pythagoras, leg squared = hypotenuse squared minus other leg squared.
2. 26 squared minus 24 squared = 676 minus 576 = 100.
3. Other leg = square root of 100 = 10 cm.
