Step-by-step explanation:
in pythagora's theorem, the hypotenuse is C, and the other sides are A and B.
assuming that the two values given are A and B, we say that a² + b² = c².
square of a number is the number multiplied by itself.
4.5² + 7.5² = c²
4.5² = 20.25 and 7.5² = 56.25
so, we add the two.
20.25 + 56.25 = c²
76.5 = c² (simplifying the left side of '=')
now, we find the square root of 76.5.
c = 8.746m
