Answer:
42.0 ft
Step-by-step explanation:
let t be the height of the tree.
<u><em>At the same time ,the measure of something </em></u>
<u><em>and its shadow are proportional</em></u> .
Then

Then
2t = 6 × 14
Then
2t = 84
Then
t = 84/2
Then
t = 42
Therefore the tree is 42 ft tall
7 - 4x = 7y
1 - 4/7x = y....y = -4/7x + 1...slope here is -4/7.
A parallel line will have the same slope
y = mx + b
slope(m) = -4/7
(2,0)...x = 2 and y = 0
now sub and find b, the y int
0 = -4/7(2) + b
0 = -8/7 + b
8/7 = b
so ur parallel equation is : y = -4/7x + 8/7 <=
