please help me !!!! trigonometric ratios !!!

Answer:
Step-by-step explanation:
If the questions is "What's x" then the answers is...
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
use CAH
Cos(x) = 46/60
x = arcCos(46/60)
x = 39.9445 °
Answer:
[tex]\displaystyle 40°[/tex]
Step-by-step explanation:
[tex]\displaystyle sec^{-1}\:1\frac{7}{23} = x; 39,94450519...° \\ \\ \boxed{40° \approx x}[/tex]
OR
[tex]\displaystyle cos^{-1}\:\frac{23}{30} = x; 39,94450519...° \\ \\ \boxed{40° \approx x}[/tex]
I am joyous to assist you at any time.
