Answer:
8
Step-by-step explanation:
Well this is a right triangle which means that you can use the Pythagorean Theorem to solve it.
a^2+b^2=c^2
The 2 lines on the other 2 sides means that those 2 sides are congruent so they are the same
C is the hypotenuse and a=b so
a squared + a squared = 16 squared = 156
that should help you get started
