Ryan is a fitout buiding contractor and needs to use equations applying pythagoras's theorem and trigonometry functions to determine wall sizes and angles.

The text on the Ryan Not Enough Space mathematics posters is shown under this diagram: 

"Ryan Contracting are fitting out their first major high-rise project.   Because a corridor was widened Ryan now needs to have a revised position for the duct offset wall approved by the architect and owner.

The proposed new position for the offset wall is shown (top left).  Calculate the length of the proposed run as shown, and the angle x.

Pythagoras' theorem is used to calculate the length of the proposed new run, and the trig (trigonometry) tan (or tanget) function to calculate the angle. Sine of cosine could also be used. See the Ryan math posters & maths posters worksheet for more details on additional questions.
