I don't know how to solve
Trava [24]
The answer would be 29* because the two measurements should be equal to 180*. So the value of one angle plus the value of the other angle equal 180. You gather all like values in the equation, then leave the x by it self by dividing. After you have the final x value, you substitute x to the initial values to give the final angle results.

Write an expression for the number or floors the building can have for a given building height. Tell what variable in your expre
vovangra [49]

Answer:

N = H / 12

H: must be in feet

Step-by-step explanation:

Declaring variables:

- Height of each floor L = 12 ft

- Total height of the building is H

- Number of floors in the building N

Developing an expression:

- The number of floors in a building can be determined by the following expression:

                                    N = H / L

                                    N = H / 12

                                   N = 0.08333*H

- it is to be noted that the units of H must also be in ft.
