Question

PLZ PLZ PLZ HELP I WILL MARK BRAINLIEST - What is the length, in units, of the hypotenuse of a right triangle if each of the two legs is 3 units?

Square root of 18 units
Square root of 27 units
3 units
6 units

Answer 1

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 2

Answer:

√18

Step-by-step explanation:

hypotenuse =√(base^2 +altitude^2)

√(3^2+3^2)=√18 units
