Solution
Solution Steps
Step 1: Identify the Trigonometric Function
To find the angle \( x \) in the right triangle, we can use the tangent function, which relates the opposite side to the adjacent side. Here, the opposite side is 28 and the adjacent side is 21.
Step 2: Set Up the Tangent Equation
The tangent of angle \( x \) is given by:
\[ \tan(x) = \frac{\text{opposite}}{\text{adjacent}} = \frac{28}{21} \]
Step 3: Calculate the Tangent Value
Calculate the value of the fraction:
\[ \frac{28}{21} = \frac{4}{3} \approx 1.3333 \]
Step 4: Use the Inverse Tangent Function
To find the angle \( x \), take the inverse tangent (arctan) of 1.3333:
\[ x = \tan^{-1}(1.3333) \]
Step 5: Compute the Angle
Using a calculator, compute the inverse tangent:
\[ x \approx 53.1^\circ \]
