Question

Please help me !!!! trigonometric ratios !!!

Answer 1

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 2

`\displaystyle 40°`

Explanation:

`\displaystyle sec^(-1)\:1(7)/(23) = x; 39,94450519...° \\ \\ \boxed{40° \approx x}`

OR

`\displaystyle cos^(-1)\:(23)/(30) = x; 39,94450519...° \\ \\ \boxed{40° \approx x}`

I am joyous to assist you at any time.
