JK = 2.4

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

= , substitute values

= ( cross- multiply )

3JK = 7.2 ( divide both sides by 3 )

JK = 2.4

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

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:
