Question

Gabriel leans a 18-foot ladder against a wall so that it forms an angle of 73° with the ground. How high up the wall does the ladder reach?

Answer 1

about 17.21 feet

Explanation:

Set your calculator to degree mode.

The figure is omitted--please sketch it to confirm my answer.

`\sin(73) = (h)/(18)`

`h = 18 \sin(73) = 17.21`
