Introduction

In the world of mathematics, equations are used to represent various relationships between variables. One such equation is $\tan^{-1}\left(\frac{8.9}{7.7}\right) = x$, which is used to find the measure of angle LKJ. In this article, we will delve into the world of trigonometry and explore the concept of inverse tangent, and how it can be used to find the measure of angle LKJ.

Understanding the Inverse Tangent Function

The inverse tangent function, denoted by $\tan^{-1}$, is a mathematical function that returns the angle whose tangent is a given value. In other words, if we know the value of the tangent of an angle, we can use the inverse tangent function to find the measure of that angle.

The Equation of Angle LKJ

The equation $\tan^{-1}\left(\frac{8.9}{7.7}\right) = x$ can be used to find the measure of angle LKJ. To solve this equation, we need to find the value of $x$ that satisfies the equation.

Using a Calculator to Find the Measure of Angle LKJ

To find the measure of angle LKJ, we can use a calculator to evaluate the expression $\tan^{-1}\left(\frac{8.9}{7.7}\right)$. By entering this expression into a calculator, we get:

$$\tan^{-1}\left(\frac{8.9}{7.7}\right) \approx 41.0^{\circ}$$

Rounding to the Nearest Whole Degree

Since we are asked to round the measure of angle LKJ to the nearest whole degree, we can round $41.0^{\circ}$ to $41^{\circ}$.

Conclusion
