Sagot :
The equation that can be used to find the measure of angle LKJ is
x = Sin⁻¹ (8.9/10.9).
what are trigonometric ratios?
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 ∠LKJ = 8.9/10.9
∠LKJ = Sin⁻¹ (8.9/10.9)
x = Sin⁻¹ (8.9/10.9)
Therefore, the equation that can be used to find the measure of angle LKJ is x = Sin⁻¹ (8.9/10.9).
