? Is there an equation that comes with this problem?
We have to find the transformation that maps preimage ABCD to A" B" C"D" .
First there is a reflection across x axis to get A'B'C'D'.
And then there is a translation of 6 units to the left and 1 unit up .
And after doing so, we will get A"B"C"D".
So out of the four options, correct option is the first option.
Pythagorean thoerem
we imagine the wall as a leg of a right triangle, the ladder is the hypotonuse and the distance from the bottom of the ladder to the wall is the other leg
so if we have a right triangle with leg length a and b and hypotnuse length c then
a²+b²=c²
so
given that one of the legs is 9ft (9 ft is the height of the triangle)
and the hypotnuse is 12 ft (length of ladder)
then say the last leg is x
so
x²+9²=12²
x²+81=144
mius 81 both sides
x²=63
sqrt both sides
x=√63
x=3√7
you should place it 3√7ft or about 7.9 or 8ft away
