Question

find the remaining sides and angles of the triangle a=4.7, b=4.4, c=5.7

A= ??? degrees
B= ??? degrees
C= ??? degrees

Answer 1

law of cosines

c^2 = a^2 + b^2 - 2 a b cos C

Answer 2

I need something more specific.

Answer 3

substitute the sides of the triangle into that equation and
find C from its cosine

after that, use law of sines to get other angles
a/sinA = b/sinB = c/sinC

where C is angle across from side c etc.
