## xoalyssaxo1 2 years ago A ladder leans against a house at a 60° angle to the ground. If the ladder extends to a length of 158 inches, what is the height of the house rounded to the nearest hundredth of an inch? http://speedcap.net/sharing/screen.php?id=files/e9/54/e954ac9077ec0c82d0ef6e7654990368.png

1. Chlorophyll

height x = 158 in * sin 60°

2. xoalyssaxo1

x= 158* 0.866025404 .866*158=136.828 inches right?

3. xoalyssaxo1

but would nearest 100th of an inch be 136.82

4. Chlorophyll

No, you need to round it up into 136.83 in

A toddler's playground has two slides on either side. The slide on the left is situated at a 45° angle to the ground and is 52 centimeters away from the base of the playground. The slide on the right is positioned at a 30° angle to the ground and is 98 centimeters away from the playground's base. What is the total length of both slides on this play I got 186.7 http://gyazo.com/5c9caf75f57e7a32f5f8d14ee403804a if you can help thanks
