we have different side lengths and thus different angles anyhow, meaning is an Scalene triangle.
Answer: Height of tree = 26 ft
Make a triangle ABC with 40 degrees angle. The shadow is the base of the triangle equals 31 feet.
Base = AC = 31
Perpendicular = CB = ?
Hypotenuse = AB
Using trigonometric equation
tan 40 (deg) = CB / AC
CB = Tan 40 x AC
CB = 0.83909 x 31
CB = 26.011
Thus the height of the tree = 26 ft
Answer:
216 + 9i
Step-by-step explanation:
Given: f(x) = 3x² + 3
+ 3x
When x = -9, f(x) equals to;
3(-9)² + 3(-9
+ 3(-9)
243 + 3(3i) - 27
243 + 9i - 27
216 + 9i
