Answer:

a=9

Step-by-step explanation:

We can use the Pythagorean theorem since this is a right triangle

a^2 + b^2 = c^2

a^2 +40 ^2 = 41^2

a^2 + 1600 = 1681

a^2 = 1681-1600

a^2 = 81

Take the square root of each side

sqrt(a^2) = sqrt(81)

a = 9

Answer:

9.

Step-by-step explanation:

Pythagoras Theorem is used in this case:

a² + b² = c²

a² + 40² = 41²

a² + 1600 = 1681

a² = 1681 - 1600

a² = √81

a = 9

9 is the third answer.
