We can write a proportion: 15 m is to 12 m as some other height
is to 20 m

So the second tree is 25 m tall.
The answer is 3.87. :)
You can simplify it.
Answer:
n=30
Step-by-step explanation:
4 15
------ = --------
8 n
using cross products
4n = 8*15
4n = 120
divide by 4
4n/4 =120/4
n = 30
Answer:
1. None of the angles
2. Is not
3. Is not
Step-by-step explanation:
We can see if the triangles are congruent by ASA (angle, side, angle)
We find ∠F in DEF by 180-(64+78)=38 and 38 doesn't equal 39 so they are not congruent.
