Question

Solving right triangle find the missing side. round to the nearest tenth number 10

Answer 1

Given a right angle triangle

As shown in the figure:

Side x is the opposite to the angle 68

Side 21 is adjacent to the angle 68

We will use the tan function to find x:

`\begin{gathered} \tan 68=(opposite)/(adjacent) \\ \\ \tan 68=(x)/(21) \\ \\ x=21\cdot\tan 68=51.9768 \end{gathered}`

Rounding to the nearest tenth

So, the answer will be x = 52
