Question

Hi, can you help me to solve this exercise, please!!

Answer 1

From the given right triangle we get that:

`\sin H=(FG)/(HF)\text{.}`

Multiplying the above equation by HF we get:

`\begin{gathered} \sin H* HF=(FG)/(HF)* HF, \\ HF\sin H=FG\text{.} \end{gathered}`

Substituting HF=7 and H=25 degrees in the above equation we get:

`\begin{gathered} FG=7\sin 25^(\circ), \\ FG\approx3.0. \end{gathered}`

Answer:

`FG\approx3.0.`
