Answer:
h=15 m
Explanation:
the formula for figuring out triangle side lengths is called the pythagorean theorem. it says a^2+b^2=c^2. c is always the hypotenuese of the triangle. we are trying to find he height not the hypotenuese so we say c^2-b^2=a^2.
17^2-8^2=h
289-64=225
h= the square root of 225
h= 15 m
