Answer:
x = 20 ft
Step-by-step explanation:
We can use similar triangles and ratios to solve
4.5 ft 6 ft
--------- = ---------------
15 ft x ft
Using cross products
4.5x = 15*6
4.5x =90
Divide each side by 4.5
4.5x/4.5 = 90/4.5
x =20
You have to translate the triangle over to where point B is lined up with point B in the second triangle. Then you can reflect over the y-axis.
So...your answer should be...
Step 1:A.
Step 2:C.

Answer:
The staircase would extends 1.20 m if the changes were made.
Step-by-step explanation:
Acording tho the statement the total heigth is 5.04 m, that is 504 cm, each steps rises 21 cm. with this information we can calculte how many steps are in the whole staircase:

To calculate how much the staircase will extend, whe have to multiply the horizontal depth times the number of steps.
using the run of 24 cm that gives us a lengt of 576 cm and if the changes were made the new length will be 696 cm.
So the staircase would extend an amount of (696 - 576), that is 120 cm, or 1.20 m, if the changes were made.
