Triangle def is similar to triangle abc
Solve for y

y = 30.9375

Step-by-step explanation:

Ok so if it is similar than that means that 37.5 is equal to y and 20 is equal to 16.5 It can also be written like this:

37.5   y

_   =   _

20     16.5

Then you cross multiply a get:

20y = 618.75

Then you divide both sides by 20 to get the variable (y) by its self:

20y = 618.75

/20           /20

Then you get your answer of:

y = 30.9375

Hope this helps and hope u have an Amazing day!!

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

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
