you can find 11 using Pythagorean theorem which would get you the square root of ten

And for question 13 you would find the square root of ten which is 3.16 which rounds up to 3.2 as your answer

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
