Answer:
Probably 5
Step-by-step explanation:
This is an extremely confusing question. Whoever wrote it most likely had a typo.
The little box in the corner of the triangle means that is 90 degrees. if that is the case, this is a simple question:
Apply pythagorean theorem (a^2 + b^2 = c^2)
In this case:
3^2 + 4^2 = x^2
x^2 = 25
x=5.
HOWEVER: the two given angles are 60 degrees and 50 degrees.
Which does not work. It creates an impossible triangle.
