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.
