Answer:
Step-by-step explanation:
Use SOH CAH TOA
Sin = Opp / Hyp
Cos = Adj / Hyp
Tan = Opp / Adj
look to see which formula fits with what we know and what we want to find
we know the angle and the Adj, and we want to find the Hyp
so use Cos, b/c it's got those in it
Cos(45) = 5 [tex]\sqrt{2}[/tex] / Hyp
[tex]\sqrt{2}[/tex] / 2 = 5 [tex]\sqrt{2}[/tex] / Hyp
Hyp = 5 [tex]\sqrt{2}[/tex] / [tex]\frac{\sqrt{2} }{2}[/tex]
Hyp = 5 [tex]\sqrt{2}[/tex] * 2 / [tex]\sqrt{2}[/tex]
Hyp = 10
X - 10 :)
