Answer:
Step-by-step explanation:
First consider the diagram:
Now, we know that
Now, the area of the triangle ABC is given by,
Answer:
2x³ -5(x²-5)
Step-by-step explanation:
2x3 − 5x2 + 25
=2x³ -5x²+25
=2x³ -5(x²-5)
Answer:
D. 900 in ^3
Step-by-step explanation:
The volume of rectangular pond would be equal to the priduct of its height, width, and depth.
Volume = Length × Width × Depth
We are given
length = 15 inch
Width = 20 inch
Depth = 3inch
Volume = 15 × 20 × 3 = 900 in ^3
Answer:
279 feet
Step-by-step explanation:
To find x, we solve using the Trigonometric function of Tangent
tan θ = Opposite/ Adjacent
θ = 64°
Length of the shadow = Adjacent = 136 feet
Height of the building = Opposite = h
Hence,
tan 64 = h/136 feet
Cross Multiply
h = tan 64 × 136 feet
h = 278.84132245 feet
Approximately, h to the nearest foot ≈ 279 feet
Therefore, the height of the building = 279 feet
