Q:

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. 68.3 by The Law of Cosines (SSS)22.9 by The Law of Cosines (SAS)10.7 by The Law of Sines (SAS)8.8 by The Law of Sines (SSA)

Accepted Solution

A:
For this case using the law of the sine we have the following mathematical relationship:
 x / sine (21) = 27 / sine (65)
 Clearing x we have:
 x = (27 / sine (65)) * (sine (21))
 x = 10.68 units
 Rounding off we have:
 x = 10.7 units
 Answer:
 10.7 by The Law of Sines (SAS)
