Question

I need help with a problem

Answer 1

2)

we will use the trigonometric ratio of tangent

`\tan (\alpha)=(O)/(A)`

where alpha is the angle , O the opposite side from the triangle and A the adjacent side

now replacing

`\tan (x)=(5)/(9)`

and solve for x

`\begin{gathered} x=\tan ^(-1)((5)/(9)) \\ x\approx29 \end{gathered}`

the measure of the angle x is 29°
