An engineer is monitoring construction of a 75-foot-long escalator. The difference in height
between the two floors being connected was origi-
nally supposed to be 40 feet, but due to a calculation
error, this figure must be reduced by 25 percent.
The angle between the escalator and the floor must
not change in order to comply with the building
code. What is the change in length in feet between
the original escalator measurement and its corrected
value?

i belive those are the ones that are under 90 degreese.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)

show us the triangle so we can answer it
