    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
