Answer:

x = 93.4° ( to 1 dec. place )

Step-by-step explanation:

Given

[tex]\sqrt{34}[/tex] cos(x - 46.7)° = 4 ( divide both sides by [tex]\sqrt{34}[/tex] )

cos(x - 46.7)° = [tex]\frac{4}{\sqrt{34} }[/tex], thus

x - 46.7 = [tex]cos^{-1}[/tex]( [tex]\frac{4}{\sqrt{34} }[/tex] ) ≈ 46.7° ( add 46.7° to both sides )

x ≈ 93.4°
