Step-by-step explanation:

<u>Given</u><u> </u><u>that</u><u>:</u><u>-</u>

  • Side AC measures 6 units
  • Side BC measures 9.5 units
  • Side AB measures 11 units

<u>To</u><u> </u><u>find</u><u>:</u><u>-</u>

  • The cosB as a decimal rounded to the nearest hundredth

<u>We</u><u> </u><u>know</u><u> </u><u>that</u><u>, </u>

{ \bigstar \: { \underline{ \boxed{ \cos( \theta ) \:  =  \sf\frac{adjecent \: side}{hypotenuse}  }}}}

<u>Solution</u><u>:</u>

\longrightarrow \rm  \cos(B)  =  \dfrac{BC}{AB}

\longrightarrow \rm  \cos(B)  =  \dfrac{9.5}{11}

\longrightarrow \rm  \cos(B)  =  \dfrac{95}{110}

\longrightarrow \rm  \cos(B)  =  0.8 63

\longrightarrow  \rm  \cos(B)   \approx \: 0.9

<u>Therefore:</u>

  • Cos B equals 0.9
