Question

Use a scientific calculator to find the values of the following.

Answer 1

For the given triangle, we have that the trigonometric functions are defined as follows:

`\begin{gathered} sinA=\frac{opposite\text{ side}}{hypotenuse}=(1)/(2)=0.5 \\ cosA=\frac{adjacent\text{ side}}{hypotenuse}=(√(3))/(2)=0.86 \\ tanA=\frac{opposite\text{ side}}{adjacent\text{ side}}=(1)/(√(3))=0.58 \end{gathered}`
