I need help i dont know how to do this

Answer:
3/4
Step-by-step explanation:
Question: Find the value of the sine for <A
C= 80m
B= 60m
A= ?
Well, since there are 3 sides you divide by three, only 2 sides are given so first add them,
80+60= 140
140/3= 46.6 also 46 6/10
Then divide by 62.13 because 140- 77.87 is that
It would lead you with 3/4
