Answer 1

Answer:

The height of the ladder is 6.9 meter

Explanation:

Given:

• angle: 60°

• opposite: 6 meter

• hypotenuse: height of ladder

As opposite and hypotenuse given, use sine rule:

$\rightarrow \sf sin(x) = \dfrac{opposite}{hypotenuse}$

$\rightarrow \sf sin(60) = \dfrac{6}{h}$

$\rightarrow \sf h = \dfrac{6}{sin(60)} = 4\sqrt{3} = 6.928 \ meters \quad \approx \ 6.9 \ meters \ \ (one \ decimal \ place)$
