The required value of the acute angle x in a right angle triangle is 20. Option A is correct.
Given that
In a right triangle, the acute angles have a relationship,
sin (2x+4) = cos(46)
To determine the value of x
<h3>What are trigonometric equations?</h3>
These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.
sin (2x+4) = cos(46) - - - - - -(1)
Since,
cos(46) = cos (90 - 44)
cos(46) = sin (44)
put it in equation 1
sin (2x+4) = sin (44)
2x + 4 = 44
2x = 44 - 4
2x = 40
x = 20
Thus, the required value of the acute angle x in a right angle triangle is 20. Option A is correct.

Answer:
None of these
Step-by-step explanation:
The two cases are for trigonometry special angles.
The cosine of an angle is given as the adjacent side length divided by the hypotenuse side length
Cos ∅ = A/H
1. The case of 45°,45°,90°
Cos x = 1 /√2
2. The case of 30°, 60° ,90°
Cos x = 1/2 or √3/2
