50. i’m sure you’re learning the proper mathematical way to do that, but my brain went ‘4+5 is 9. that’s 10 times less than 90’
The correct answer is vertex.
Vertex is minimum(lowest) point when parabola opens upwards, it is the maximum(highest) point when parabola opens downward, it is the farthest point on left if parabola opens right and farthest point towards right if parabola opens left.
So the correct answer to this question is option D
Answer: 30 feet
--------------------------------
Work Shown:
x = height of tree in feet
The larger triangle, and the smaller triangle that fits inside the larger, are similr triangles.
So we can form the proportion
x/5 = 48/8
Note how x/5 is the result of dividing the larger vertical side (x) over the smaller vertical side (5)
The same applies with 48/8. The larger triangle's horizontal side is 8+40 = 48. The corresponding horizontal side for the smaller triangle is 8
Cross multiply to solve for x
x/5 = 48/8
8*x = 5*48
8*x = 240
8*x/8 = 240/8
x = 30
The tree is 30 feet tall
