Step-by-step explanation:
<u>The travel is 2 circumferences:</u>
- 2C = 2*2πr = 4πr = 4*3.14*7 = 87.92 cm
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.
