6. What is the length of the hypotenuse of the triangle when x = 3
Round your answer to the nearest tenth.

Answer:
17.1
Step-by-step explanation:
Substitute 3 in place of x first, find the last side of the triangle using the Pythagorean theorem.
2x = 2*3 = 6
5x+1 = 5*3+1 = 16
[tex]a^{2} +b^{2} =c^{2} \\\\6^{2} +16^{2} =c^{2}\\17.1 = c[/tex]
