Answer:
25 ft
Step-by-step explanation:
The 2 triangles are similar hence the ratios of corresponding sides are equal, that is
=
= 5
multiply both sides by 5
x = 5 × 5 = 25
The height of the tree is 25 ft
4 and -2.5
You can get this by first factoring the equation.
(2x + 5)(x - 4)
Then set both equal to zero and solve individually.
