Answer:
58 degree
Step-by-step explanation:
the total degree of the three interior angles together of a triangle = 180
here 2 sides are given so to find the 3rd angle we can just add the other 2 angles and subtract it from 180
so it'll be
[tex]65 + 57 = 122[/tex]
[tex]180 - 122 = 58 \: degrees[/tex]
answer = 58 degree
