How long will a section of a railroad track be if it rises 6.8m for a run of 125.6 m

The length of the section will have 125.8 m

Step-by-step explanation:

Right Triangle

The section of the railroad track rises a height of h=6.8 m for a horizontal run of x=125.6 m.

The height and the horizontal run are the legs of a right triangle which hypotenuse L is the required length of the section of the railroad track.

Applying Pythagora's Theorem:

The length of the section will have 125.8 m

24

step-by-step explanation:

i assuming that 2 sides are 6 the other 2 sides are 4 cm so 6 times 4 is 24 : )

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
