Answer:
10
Step-by-step explanation:
The triangle in the pic is a right-angled triangle. And in right-angled triangles , Pythagorean Theorem. So , according to Pythagorean Theorem
[tex]Base^{2} +Perpendicular^{2} =Hypotenuse^{2}[/tex] where 'c' is the hypotenuse and 'a' & 'b' are the other two sides.
Using Pythagorean Theorem ,
[tex]Hypotenuse^{2} = 8^{2} +6^{2} =64+36=100\\=>Hypotenuse = \sqrt{100} =10[/tex]
