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.
