14.Find the missing side length to the near tenth.х64°6A. 3.1B. 2.6C.13.7D.3.8

Answer 1

90+64+y=180 (sum of angle in a triangle)

The third angle is 26

`\begin{gathered} (x)/(\sin26)=(6)/(\sin 90) \\ (x)/(0.4384)=(6)/(1) \\ \text{cross multiply} \\ x*1=6*0.4384 \\ x=2.6\text{ nearest tenth} \end{gathered}`
