Answer:
B. 41
Step-by-step explanation:
Missing sides of a right triangle can be found using the Pythagorean Theorem. The formula for the Pythagorean Theorem is: a² + b² = c², where 'a' and 'b' represent the legs of the triangle and 'c' represents the hypotenuse. Since the leg lengths of the right triangle are given as 9cm and 40cm, we can set up the following equation:
9² + 40² = c² or 81 + 1600 = c²
1681 = c²
Take the square root of both sides: √1681 = √c²
c = 41 (answer choice B)
