Answer 1

The height of the ladder is 6.9 meter

Step-by-step explanation:

Given:

• angle: 60°

• opposite: 6 meter

• hypotenuse: height of ladder

As opposite and hypotenuse given, use sine rule:

`\rightarrow \sf sin(x) = (opposite)/(hypotenuse)`

`\rightarrow \sf sin(60) = (6)/(h)`

`\rightarrow \sf h = (6)/(sin(60)) = 4√(3) = 6.928 \ meters \quad \approx \ 6.9 \ meters \ \ (one \ decimal \ place)`
