For each triangle shown below, determine whether you would use the law of sines or law of cosines to find angle x. then find angle x to the nearest tenth. a 90.1 by the law of sines (sas) b. 75.6 by the law of cosines (sas) c. 46.9 by the law of cosines (sss) d. 37.2 by the law of sines (ssa)

For the question above we can use the law of sine that states;

a/sinA = b/sinB = c/sinC
 Where a is the opposite side of angle A
             b is the opposite side of angle B
             c is the opposite side of angle C

x/sin63 = 65/sin40

x = 65(sin63)/sin40

   = 57.9154/0.6429
     = 90.10

The answer is A) 90.1 by The Law of Sines (SAS)

Od. 130 degrees because if you add them together you get the 130
