Question

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

Answer 1

Given:

$\begin{gathered} \text{Side XY=7} \\ \angle Z=90^{\circ} \\ \angle X=35^{\circ} \end{gathered}$

As, this is right angled triangle

$\begin{gathered} \text{SideXZ}=\text{side XY}\cdot\cos (35^{\circ}) \\ =7\cdot0.8192 \\ =5.7344 \end{gathered}$

So, the side XZ = 5.7 ( nearest to tenth)
