Answer:
98 cm²
Step-by-step explanation:
Lateral surface area = surface area of the sides ONLY of the object
⇒ lateral SA = B + C + D = 35 + 28 + 35 = 98 cm²
Answer:
The power of horse is: P = 72000 W
Step-by-step explanation:
Given
To determine
P = ?
Using the formula

The ⋅ in the formula represents a scalar product, defined by:

The angle Ф is zero because F and v are are parallel.
Thus the cosine is 1.
Therefore,
P = (1800) (40.0)
P = 72000 W
Hence, the power of horse is: P = 72000 W
Angle ABC = 48
Angle PBC = 24
Angle A + Angle C = 180-24. Angle A = Angle C
Angle C = 132/2 = 66
Angle PCD = 66-24 = 42 degrees
