Answer:
- Only Drawing D has KL being a symmetrical segment.
- Drawings A, B and C have no axis of symmetry.
- Tylko rysunek D ma KL będący segmentem symetrycznym.
- Rysunki A, B i C nie mają osi symetrii.
Step-by-step explanation:
English Translation
In which drawing was the symmetrical segment of KL drawn? Which of these letters has no axis of symmetry?
Solution
The attached image to the question is presented in the attached image to this Solution.
Symmetry is a concept where a figure/shape has half of its part being a mirror image of the other part.
About the line or axis of symmetry, the structure or figure can be rotated at right angles or whole number multiples of right angles and the resulting structure is still the same as the one we started with.
Of the 4 drawings, only drawing D satisfies this conditions/criteria. And Hence, it is the only drawing amongst the four with an axis of symmetry.
In Polish/Po polsku
Załączony obraz do pytania jest przedstawiony na załączonym obrazku do tego rozwiązania.
Symetria to koncepcja, w której figura / kształt ma połowę swojej części stanowiącą odbicie lustrzane drugiej części.
W odniesieniu do linii lub osi symetrii, strukturę lub figurę można obracać pod kątem prostym lub wielokrotności liczby całkowitej pod kątem prostym, a wynikowa struktura jest nadal taka sama jak ta, od której zaczęliśmy.
Z 4 rysunków tylko rysunek D spełnia te warunki / kryteria. I dlatego jest to jedyny rysunek wśród czterech z osią symetrii.

Answer: Crayfish, 25 s
Step-by-step explanation:
Given
The length of race is 60 cm
Flicker gets a 10 cm head-start
Cray fish covers 6 cm in 5 s i.e. its speed is
Flicker covers 4 cm in 5 s, its speed is
Time taken by Cray fish to cover the race is
Time taken by flicker to cover race with 10 cm head start
Time taken by crayfish is less. Hence, crayfish wins the race
When they both covers the same distance, they tied momentarily i.e.
After 25 s, they tied the race.
