1) a=7, A=49°

2) a=7, c=16

Answer 1

1) sin(49) = 7/c tan(49) = 7/b
c = 7/sin(49) = 9.28
b = 7/tan(49) = 6.09

2) a^2 + b^2 = c^2
49 + b^2 = 256
b^2 = 207
b = 14.39

Answer 2

use the sin rule for this : a/sinA = b/sinB=c/sinC

i might be wrong it could also be the inverse sinA/a etc.
anyway that you can look up in your textbook
