Answer:
Height of the pine tree = 60 in.
Step-by-step explanation:
Since, triangle formed by the tip of the tree and tip of the shadow of the tree will be similar to each other,
By the property of similarity, corresponding sides of the similar triangles will be proportional.
If d = 12 inches,
x =
x = 60 in.
Therefore, height of the pine tree will be 60 in.
Since those lines are parallel, we know that A + B = 180°
So, we have:
8x + 74 + 2x + 56 = 180
10x + 130 = 180
10x = 180 - 130
10x = 50
x = 5
B = 2x + 56
B = 10+56=66
(To check:
A = 8x + 74
A = 40+74=114
114+66=180)
