Answer:
27
Step-by-step explanation:
45 x 45 - 36 x 36 = 729 the square root of 729 is 27
a = 27 m is the answer.
a = ?
b = 36 m
c = 45 m
According to the Pythagoras theorem,
a² + b² = c²
a² + 36² = 45²
a² + 1296 = 2025
a² = 2025 - 1296
a² = 729
a = 27 m
∴ a = 27 m is the length of the missing leg.
