Find a. Round to the nearest tenth.

Answer:
Step-by-step explanation:
Using the Law of Sines is the way to go, but before you we use it we need the measure of angle A.
180 - 102 - 28 = A so
A = 50 degrees. Now setting up the Law:
[tex]\frac{sin50}{a} =\frac{sin28}{27}[/tex] and cross multiply to get
27sin50 = asin28 and
[tex]\frac{27sin50}{sin28}=a[/tex] so
a = 44.1 cm
