Final answer:
To find the value of x in the parallelogram QRST, use trigonometry. In this case, consider Figure 4.17 and use the cosine ratio to find the magnitude of TL.
Step-by-step explanation:
In order to find the value of x in the parallelogram QRST, we need to use trigonometry. Let's consider Figure 4.17. We can use trigonometric ratios to determine the magnitude of T₁ and TR. From the figure, we can see that TLX is a right triangle. We can use the cosine ratio to find TL: cos(5.00°) = TL/4.00. Solving for TL, we get TL ≈ 3.9992.
