Answer:
1.04 inch
Step-by-step explanation:
Given: Old house has a basement stairways with 7.25 inch vertical riser and 7 inch horizontal treads.
Remember; horizontal treads is known as run in steps.
Now, calculating the slope of the stairways.
Formula: ![Slope= \frac{Rise}{Run}](https://tex.z-dn.net/?f=Slope%3D%20%5Cfrac%7BRise%7D%7BRun%7D)
Rise= 7.25 inch
Run= 7 inch.
Subtituting the value in the formula
Slope=
(∵ Round to two decimal)
∴ Slope of stairways is 1.04.
A = 0.635
b = 8.57......
c = 17.5
d = 0.733....
Answer:
1. 1
1. 13π.
--
20
explain:
1. 1 because any any non-zero expression raised to the power of 0 equals 1
13π.
2. --. because to convert into radian measure multiply by. π
20. ----
180°
The slope would be -x (down one over one) because parallel lines always have the same slope. I hope this helped you :)
Step-by-step explanation:
2x + 100 = 90
x = -5
Angle A = 45 - 5 = 40.
