Question

Find VX.Write your answer as an integer or as a decimal rounded to the nearest tenth. VX = ___

Answer 1

It is given that in triangle VWX, angle X is 63 degrees and VW is 8

Use trigonomtric ratio of sin to get:

$\begin{gathered} \sin 63=\frac{8}{VX} \\ VX=\frac{8}{\sin 63} \\ VX=8.9786099 \\ VX\approx9 \end{gathered}$

Since when rounded to tenth place it gives 9.

Hence the value of VX is 9 units.
