Answer:
8.1
Step-by-step explanation:
Since we dealing with right triangles, we are going to use pythagoern theorem.
[tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex], where a and b are the two legs and c is the longest side or the slanted side( known as hypotunese.)
Let plug in the numbers
4^2+ b^2=9^2
16+b^2=81
b^2=65
sqr root of 65 is about 8.1
