Answer:
Step-by-step explanation:
The Pythagorean Theorem is c^2=a^2+b^2. This can be applied to right triangles
h^2=x^2+y^2
Meaning the hypotenuse is equal to the square root of the sum of its squared sides.
In this case:
14^2=3^2+x^2
x^2=14^2-3^2
x^2=196-9
x^2=187
x=(187)^(1/2)
x=13.7 rounded to nearest tenth
