The figures have corresponding sides that are proportional, therefore, they are similar figures.
<h3>What are Similar Figures?</h3>
When two figures are similar to each other, the corresponding sides are proportional to each other.
The two figures given have two opposite sides that are parallel and congruent to each other. Therefore:
DA/VS = 21/7 = 3
AB/ST = 15/5 = 3
Thus, we can conclude that since their corresponding sides are proportional, therefore, they are similar to each other.

Step-by-step explanation:
Given that an office has 30 computers. Seventeen of the 30 are Macintosh, and the remaining thirteen are windows.
When two computers are randomly selected without replacement
no of ways of selection = 
No of ways of selecting one window and one Mac = 
Prob that the sample contains exactly one windows machine and exactly one Macintosh=
Answer:
Step-by-step explanation:
Answer:
A, B, C
Step-by-step explanation:
none of the 4 options changes the shape.
but D changes the size.
C is the only one that also maintains the orientation of the triangle - it only shifts its position.
A and B maintain size and shape, but they do change its orientation.
Answer:
y -15 = -3(x +2)
Step-by-step explanation:
The slope will be ...
m = (y2 -y1)/(x2 -x1)
m = (-18 -15)/(9 -(-2)) = -33/11 = -3
Point-slope form is ...
y -y1 = m(x -x1) . . . . . line with slope m through point (x1, y1)
Using the first point, the equation is ...
y -15 = -3(x +2)
