Answer:

Step-by-step explanation:

sum of ngles of triangle=180

90+39+A=180

129+a=180

A=180-129

apply the some rule:

since 39 = opp/hyp

sin39=16/c

<h2>c= 16/sin39 = 25.42 ≅ 25.4 rounded to the nearest tenth</h2>

sin 51 = opp/hyp

sin51=a/25.42415166

<h2>a=19.8 ( rounded to the nearest tenth)</h2>
