Answer 4

wait a = 68.7?

Answer 5

it is actually angle A

Answer 6

thats what i thought

Answer 7

then b =59.3

Answer 8

type error
\[\cos A=\frac{ b^2+c^2-a^2 }{ 2bc }\]

Answer 9

use sine formula to find other angle

Answer 10

what other angle c= 52

Answer 11

\[\frac{ c }{ \sin C }=\frac{ a }{ \sin A }\]

Answer 12

i got 52
