Step-by-step explanation:
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 length is 17 and x=5
13 times 3x+2 = 221 so solve by dividing 221 by 13= 17.
Now we know that 3x+2= 17 so 3x= 15
x=5
hi,
Express the ratios in fractional form, that is
= ( cross- multiply )
y + 3 = k(y + 5) ← distribute
y + 3 = ky + 5k ( subtract ky from both sides )
y - ky + 3 = 5k ( subtract 3 from both sides )
y - ky = 5k - 3 ← factor out y from each term on the left side
y(1 - k) = 5k - 3 ← divide both sides by (1 - k)
y = 5k- 3
____
1 - k
