The equation that can be used to find the measure of angle LKJ Ā is
x = Sinā»Ā¹ (8.9/10.9).
Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle.
As we know that
sine of an angle = perpendicular/hypotenuse
Sine of ā LKJ = 8.9/10.9
ā LKJ Ā = Sinā»Ā¹ (8.9/10.9)
x = Sinā»Ā¹ (8.9/10.9)
Therefore, the equation that can be used to find the measure of angle LKJ is x = Sinā»Ā¹ (8.9/10.9).
