Answer:
x=3.4
Step-by-step explanation:
Use the Pythagorean theorem:
[tex]a^2+b^2=c^2[/tex]
a and b are the legs and c is the hypotenuse (x)*
Insert the values:
[tex]3^2+1.6^2=x^2[/tex]
Simplify exponents
[tex]9+2.56=x^2[/tex]
Simplify addition:
[tex]11.56=x^2[/tex]
Find the square root:
[tex]\sqrt{11.56}=\sqrt{x^2}[/tex]
[tex]3.4=x\\x=3.4[/tex]
Finito.
*The hypotenuse is the side opposite the 90° angle and the longest side of a triangle, always.
