Lines m and n are parallel.

Lines m and n are parallel. Lines k and l intersect lines m and n to form a triangle. At the intersection of lines k, l, and m, clockwise from top left, the angles are 50 degrees, blank, 55 degrees. In the triangle the bottom left angle formed by lines k and n is 1.

What is Measure of angle 1?
35 degrees
50 degrees
55 degrees
75 degrees

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

try looking in the very back of the book : )
