- pythagorean theorem
- A construction worker is participating in building a new apartment complex. To help install a window that's 15 feet high, he needs to get a ladder to reach where it is. Since he's 10 feet away from the wall, he needs to figure out how long the ladder should be from where he is.
- He finds out that the ladder should be 18.0 ft. 10^2 + 15^2 = 18.0
- x = 18.0 ft
- x
- 10 ft
- tan
- 15 ft
- The measure of A was found to be 62.6 degrees using tan. tanA = 15/10 , A = tan^-1(15/10)
- A coworker who was assigned to work on the other side of the building needs to make his build congruent to the original one. Due to that, he asks what the measure for angle A was in order to replicate it.
- A = 62.6

- 18.0 ft
- 10 ft
- 15 ft
- cos
- The measure of x was found to be 16.2 ft using cos.cos40/1 = x/20
- Another construction worker is working on another part of the complex. He came across a triangle that only had the measurements of the hypotenuse and angles known. He is assigned to figure out the other two side lengths.
- x = 16.2 ft
- 40
- 20 ft
- x
- y
- sin
- The side length of y is found to be 11.8 ft using sin.sin40/1 = y/20
- After finding the one side length, he moves on to find the remaining side length.
- y = 11.8 ft
- 40
- 20 ft
- 16.2 ft

- 45-45-90 triangle
- 45
- Somewhere else along the building, someone is working with a 45-45-90 triangle. He needs to find out the length of the hypotenuse, knowing both of the legs are 6 ft.

- x
- x = 6√2
- 45
- Using basic 45-45-90 triangle rules, he finds that the hypotenuse is 6√2 ft
