Question

Find a. Round to the nearest tenth.

Answer 1

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:

$\frac{sin50}{a} =\frac{sin28}{27}$  and cross multiply to get

27sin50 = asin28 and

$\frac{27sin50}{sin28}=a$ so

a = 44.1 cm
