Answer:
slope = -
Step-by-step explanation:
note that BC is perpendicular to AB, hence the slope of BC is the negative reciprocal of the slope of AB
= -
= -
For this case, the first thing we must do is find the scale factor.
For this, we use one of the dimensions. We will use the width of the photo.
We have then:
Then, we look for the value of the height of the new photo. To do this, we multiply the scale factor by the original dimension.
We have then:
Answer:
the new height will be:
d.168 inches
