The measure of the angle formed by the roof and the floor of the attic is 22.62 degrees.
Right angle triangle are triangle that has one of its angles as 90 degrees. The angles formed can be found using trigonometric ratios.
Therefore,
tan x° = opposite / adjacent
tan x° = 5 / 12
tan x° = 0.41666666666
x = tan⁻¹ 0.41666666666
x = 22.6198649482
x = 22.62°
Therefore, the measure of the angle formed by the roof and the floor of the attic is 22.62 degrees.
