Answer:
68.2
Step-by-step explanation:
You can use a^2+b^2=c^2 to find the length of the missing side, where c^2 is the hypotenuse (side 14).
5^2+x^2=14^2
25+x^2=196
x^2=196-25=171
x=13.0 (rounded)
Next, use one of sin or tan to find the missing angle.
Sin0=opposite/hypotenuse
Sin0=13/14
0=sin^-1(13/14)
0=68.213 (rounded)
