Answer:
Step-by-step explanation:
(look at the picture)
We have opposite and adjacent. Therefore we must use the tangent:
[tex]\tangent=\dfrac{opposite}{adjacent}[/tex]
[tex]adjacent=500\\opposite=x\\\tan10^o\approx0.1763[/tex]
Substitute:
[tex]\dfrac{x}{500}\approx0.1763[/tex] multiply both sides by 500
[tex]x\approx88.15\to x\approx88.2[/tex]
