Question

What is the length of EC round to the nearest tenth of a foot

Answer 1

we must use trigonometric ratios, which applies for right triangles

on this case we will use

`\tan (\alpha)=\frac{\text{opposite}}{\text{adjacent}}`

where alpha is the angle, opposite is the opposite side of the angle and adjacent the andjacent side of the angle different to hypotenuse

so replacing

`\tan (44)=(x)/(2.8)`

and solving for x

`\begin{gathered} x=2.8\tan (44) \\ x=2.7039\approx2.7 \end{gathered}`

the measure of x-side is 2.7 ft
