Answer:
The polygons are similar.
Step-by-step explanation:
By definition, the corresponding sides and angles of similar polygons must be in some constant proportion.
Therefore, we can find the ratio between corresponding sides to see if that ratio is maintained.
The side marked 3 cm in the smaller figure corresponds with the side marked 3.75 cm in the larger figure. This proportion is
.
The side marked 5 in the smaller figure corresponds with the side marked 6.25 cm in the larger figure. This proportion is
.
If these polygons are similar, these proportions must be equal.

Checking, we see that these proportions are equal, and therefore the polygons are similar.
Answer:
15
Step-by-step explanation:
90 - 30 = 60
60 - 45 = 15

Answer: Choice H
y = -2x+3
=========================================================
Explanation:
Start at any point you want on the diagonal line. Notice how we move down 2, right 1 to get to a neighboring point. This "down 2, right 1" motion determines the slope
- rise = go down 2 units
- run = go right 1 unit
slope = rise/run = -2/1 = -2
So m = -2 is the slope
Another way to find the slope is to use the slope formula for any two points on that diagonal line.
The y intercept is 3 because this is where the diagonal line crosses the y axis. This means b = 3.
---------------------
To summarize, we found that m = -2 is the slope and b = 3 is the y intercept.
We go from y = mx+b to y = -2x+3
