Answer:
There isn't a way to prove that the triangles are similar.
Explanation:
Two triangles are similar if they have the same interior angles and the corresponding sides are proportional.
So, to prove that the triangles are similar we can use:
SSS: The three corresponding sides are proportional
SAS: Two sides are proportional and the angle between them is equal
AA: Two angles have the same measure.
In this case, the yellow angles are equal because they are vertically opposite. They are formed by two lines that intersect. 
On the other hand, the side with length 3.6 is corresponding with the side with length 9 but the side with length 4.8 is not corresponding with the side with length 12.
Then, there isn't a way to prove that the triangles are similar.

Answer: r= G/dh
Step-by-step explanation:
G= rdh
For r divide dh both sides
G/dh = rdh/dh
G/dh = r
 
        
             
        
        
        
Answer:
29.5 mm
Step-by-step explanation:
We are told that the average monthly rainfall for 6 months was 28.5 mm.
Thus, total for the 6 months = 28.5 × 6 = 171 mm
Now, we are told that it rained 1 mm extra each month. 
So extra for the six months = 1 × 6 = 6mm
New total for 6 months = 171 + 6 = 177 mm
So, new average for 6 months = 177/6 = 29.5 mm
