Answer: Im pretty sure its x = 4.472135955
Step-by-step explanation:
DISCLAIMER: I may be wrong I am kind of rusty.
You got to use the Pythagorean theorem (a^2 + b^2 = c^2) to answer this.
First you label your triangle by putting the hypotenuse as "c" the other known value as "b" and the unknown value as "a".
Now you input the answers into the equation.
x^2 + 4^2 = 6^2
Now answer the known values.
x^2 + 16 = 36
Now subtract by 16 to get rid of the sixteen.
x^2 + 16 -16 = 36 -16
x^2 = 20
Now to get rid off the ^2 find the square root.
x = 4.472135955
