Answer:

a

Step-by-step explanation:

Using Pythagoras' identity on the right triangle

let x be the other leg to be found, then

155² = 124² + x²

24025 = 15376 + x² ( subtract 15376 from both sides )

8649 = x² ( take the square root of both sides )

\sqrt{8649} = x

Hence x = 93 cm ← length of other leg → a
