Which equation can be used to find the measure of angle LKJ? cosāˆ’1(StartFraction 8. 9 Over 10. 9 EndFraction) = x cosāˆ’1(StartFraction 10. 9 Over 8. 9 EndFraction) = x sināˆ’1(StartFraction 10. 9 Over 8. 9 EndFraction) = x sināˆ’1(StartFraction 8. 9 Over 10. 9 EndFraction) = x.

Sagot :

The equation that can be used to find the measure of angle LKJ Ā is

x = Sinā»Ā¹ (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 āˆ LKJ = 8.9/10.9

āˆ 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).
