Question

Find x in each triangle.
PLZ HELP!!!

Answer 1

x=3.4

Explanation:

Use the Pythagorean theorem:

`a^2+b^2=c^2`

a and b are the legs and c is the hypotenuse (x)*

Insert the values:

`3^2+1.6^2=x^2`

Simplify exponents

`9+2.56=x^2`

Simplify addition:

`11.56=x^2`

Find the square root:

`√(11.56)=√(x^2)`

`3.4=x\\x=3.4`

Finito.

*The hypotenuse is the side opposite the 90° angle and the longest side of a triangle, always.
