Let’s call the length of the hypotenuse h and the lengths of the other 2 sides, forming the right angle, a and b.
Then the formula gives us…
a^2 + b^2 = h^2
Rearranging gives…
a^2 = h^2 - b^2
a = [h^2 - b^2]^0.5
In this problem
a is the unknown
b = 4 units
and h = 9 units
Therefore we have…
a = [9^2 - 4^2]^0.5
a = [81–16]^0.5
a = 65^0.5
a = 8.062 units
Answer:
√18
Step-by-step explanation:
hypotenuse =√(base^2 +altitude^2)
√(3^2+3^2)=√18 units
