AY=6, CY=15, and YD= 4, what is the measure of BY?

6/15 = 4/x

6x = 60

x= 10 which is BY

BY = 10 ANSWER

hopefully this helps.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

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
