Answer:
C. Both of the above answers
Step-by-step explanation:
13 = -6(-2) + 1
13 = 12 + 1
13 = 13
7 = -6(-1) + 1
7 = 6 + 1
7 = 7
Q. how many factors does 15 have?
1, 3, 5, 15 so 15 has 4 factors
Answer:
c = 27.9
B = 62.13°
C = 89.90°
Step-by-step explanation:
We are given the following values:
A= 121.59°, a = 27.9 cm, b = 52.6 cm
a) Finding side c
We would use Pythagoras Theorem
c² = a² + b²
c = √(a² + b²)
c = √(27.9² + 52.6²)
c = 59.54cm
≈ Approximately = 59.5cm
b) Finding B
We would be using Cosine rule to find Angle B
Cos B = a² + b² - c²/2ab
B = arc cos ( a² + c² - b²/2ac)
B = arc cos( 27.9² + 59.5² - 52.6²/ 2 × 27.9 × 59.5)
B = 62.13268°
B = 62.13°
c) Finding C
We would be using Cosine rule to find Angle C
Cos C = a² + b² - c²/2ab
C = arc cos ( a² + b² - c²/2ab)
C = arc cos( 27.9² + 52.6² - 59.5²/ 2 × 27.9 × 52.6)
C = 89.9°
It's normally measured in pounds or kilograms.
Answer:
33.4 m^3
Step-by-step explanation:
The edge length of the base is 1/4 of the perimeter, so is ...
(10.3 m)/4 = 2.575 m
Then the area of the base is the square of this, or ...
B = (2.575 m)^2 = 6.630625 m^2
The volume is ...
V = (1/3)Bh = (1/3)(6.630625 m^2)(15.1 m) ≈ 33.4 m^3
The volume of the pyramid is about 33.4 cubic meters.
