Answer:
a = 
Step-by-step explanation:
Using the rule of exponents
× 
= 
, then
x × 
= 
= 
= 
, so
= 
Since the bases on both sides are x, then equate the exponents.
a =
By using the concepts of <em>direct</em> and <em>inverse trigonometric</em> expressions, the angles that represents the <em>trigonometric</em> function cos 5/6 are θ₁ ≈ 33.557° and θ₂ ≈ 326.443°.
<h3>How to determine the possible angles of a given trigonometric relationship</h3>
Cosine are <em>trigonometric</em> functions whose period is 360°. Cosine is <em>positive</em> both for the <em>first</em> and <em>fourth</em> quadrants. Thus, the two angles associated to the given <em>trigonometric</em> expression are by inverse <em>trigonometric</em> functions:
θ₁ ≈ 33.557°, θ₂ ≈ 326.443°
