If a staircase has 8 inches of rise for every 12 inches of thread, what is the slope of the staircase?

14.4 inches ( to 1 decimal place)

the rise and tread are at right angles to each other and the slope is the hypotenuse of the right triangle formed

using Pythagoras' identity

slope = √(8² + 12²) = √(64 + 144) = √208 = 14.4 ( to 1 dec. place)
