60.2
Step-by-step explanation:
a^2 + b^2 = c^2
40^2 + 45^2 = c^2
1600 + 2025 = c^2
3625 = c^2
the square root of 3625 is 60.2
Answer:
60.2 metres
Pythagoras formula = square of b plus squar of c = square of a
let b be 40 and let c be 45
40^2 + 45^2 = a^2
1600 + 2025 = a^2
3625 = a^2
square root of 3625 = a
60.2 meters = a
