I need to find side c

The value of the hypotenuse is C = 11.73
We can see that C is the hypotenuse of the right triangle.
We can see that the top angle measures 43°, and the opposite cathetus to that angle measures 8 units.
Then we can use the rule:
Sin(a) = (opposite cathetus)/(hypotenuse).
Replacing what we know:
Sin(43°) = 8/C
Solving for C:
C = 8/Sin(43°) = 11.73
The value of the hypotenuse is C = 11.73
