PLEASE HELP!! Theres two questions

John has a 12 foot ladder. He wants to lean it against a wall. He needs the base of the ladder to be 6 feet from the base of the wall. What is the measure of the angle formed with the ground? (number only. do not include the degree sign or the word degrees)

My office is 10 ft by 12 ft. I want to buy border for the top of my wall. I have a 3ft door on a 10 ft wall and a 3 ft window directly across from it. How much wallpaper border should I buy? (number only, do not label your answer)

Answer 1

1) 90

2) 38

Explanation:

1) look at the attached diagram

As you can see, the floor and the wall must meet at a 90° angle.

2) Perimeter of office: 10 + 12 + 10 + 12 = 44

Subtract the door and windows' lengths:

44 - 3 - 3 = 38 ft.
