Question

Need help trying to solve problem. I do not understand the step process.

Answer 1

it is a right triangle ebcase an angle is 90°

so, we can use trigonometric ratios

we will use sine

`\sin (\alpha)=(O)/(H)`

where alpha is the angle, O the opposite side from the angle and H the hypotenuse o the triangle

then, replacing

`\sin (66)=(x)/(4)`

we use the angle 66° becase we need to find x and x is the opposite side from it

now solve the expression for x

`\begin{gathered} x=4\sin (66) \\ \end{gathered}`

and calculate

`x=3.65`

The value of x is 3.65m
