In a right triangle, the acute angles have the relationship sin (2x+4)=cos(46).
Elis [28]

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
