It is B SAS. Let me know if you want and explanation
Answer:
9 m
Step-by-step explanation:
Suppose AB is the ladder. AC is the height of the window above the ground and BC is the distance of the foot of ladder from the wall.
The triangle ABC is right angled at C.
∴ AB² = AC² + BC²
=> 15² = 12² + x²
=> 225 - 144= x²
=> 81 = x²
=> 9 = x
- Hence, distance of the foot of the ladder from the wall is 9 m.
I think it is hexagon. It says which polygon at the bottom, and hexagons have six sides like the figure above.
Median is middle value, mode is number that appears the most.
4 +5 +7+7+8+10 = median = 7, mode = 7
