Question 413812: Hello,
I have a ladder that is 55' in length leaning against a wall, which I believe is the hypotenuse. The angle where the ladder meets the street is 55 degrees. I need to find the length of the other two sides of the triangle. I wasn't good at math 30 years ago and it hasn't gotten any better. Thanks in advance for your help.
Best regards,
ML
