Question

In the figure XYZ ~ ABC.Find cosB, tanB, and sinB.Round your answers to the nearest hundredth.

Answer 1

we have the following;

1. Cos B:

`\begin{gathered} CosB=(a)/(h) \\ CosB=(15.4)/(17)=0.91 \end{gathered}`

2. Tan B:

`\begin{gathered} TanB=(o)/(a) \\ TanB=(7.2)/(15.4)=0.48 \end{gathered}`

1. Sin B:

`\begin{gathered} SinB=(o)/(h) \\ SinB=(7.2)/(17)=0.42 \end{gathered}`
