Sagot :

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  :)
