Answer: Length of shorter tree = 7.2 feet .
Step-by-step explanation:
Given : Height of two trees as 50 feet and 20 feet.
At same time the angle made by sun rays would be same for both trees.
Both trees are vertical to the ground making right angle so triangles made by both triangles must be similar.
Corresponding sides of similar triangles are proportional.
So 
So, Length of shorter tree = 7.2 feet .
The point-slope form:

We have:

Substitute:

Answer: C. y - 5 = 3(x + 1)
Answer:

Step-by-step explanation:
When taking a square root and making it a radical, we need to list out it's factors and find which one we can take the square root of.
The factors of 40 are:
1, 2, 4, 5, 8, 10, 20, 40.
Out of these, we need to look for one that we can find the square root of.
We know that the square root of 4 is 2.
Therefore, we can make
into
.
The square root of 4 is 2. Therefore, we can put that outside the radical.
.
Hope this helped!
