Answer:
6.5 units
Step-by-step explanation:
We are given that
Two adjacent sides of right triangle
Suppose a,b and c are sides of right triangle.
squared units
square units.
Length of third side,c=x units
We have to find the length of third side of the triangle.

By using Pythagoras theorem



Hence, the length x of the third side of the triangle=6.5 units
The answer is D, y+4 = -6(x+2).
Just plug the information into the point slope formula which is, y-y1 =m(x-x1).
