The required value of x in the right-angle triangle is 13.16.
Given that,
In right angle triangle ABC
AB = perpendicular = x ft
Angle C = 47 °
AC = hypotenuse = 18 ft
<h3>What are trigonometric equations?</h3>
These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.
Here, in the right triangle ABC
sinx = perpendicular / hypotenuse
sin( 47° ) = AB / AC
0.73 = x / 18
x = 18 * 0.73
x = 13.16
Thus, the required value of x in the right-angle triangle is 13.16.
