Answer:
Oh my god im literally so glad u asked this. because i know the answer lol. ok the answer is UR MOM
Step-by-step explanation:
If you draw this, you'll see it forms a triangle, with the ladder as the hypotenuse. We're given the two side measurements, so we can easily use Pythagorean theorem to find the ladder length (x):
(12^2 + 4.8^2) = x^2 .... x = 12.92ft
Answer: 12
==============================
Explanation:
Multiply the corresponding coordinates of the vectors
4*11 = 44
1*2 = 2
5*(-6) = -30
Then add up the results: 44+2+(-30) = 42-30 = 12
The dot product of two vectors is always a scalar value.

Medians are the line segments that divides a side of Triangle into two equal parts, each having equal length. and since triangles have 3 sides, they have 3 medians as well.
