Answer:
The length of the base edge is 3 cm
Step-by-step explanation:
Volume of square pyramid =
Where B = area of square base
H = Height
Let the length of base edge be x
Area of base =
Height of pyramid = 5 cm
So,Volume of square pyramid =
We are given that The volume of a square pyramid is 15 cubic centimeters.
So,
x=3
Hence the length of the base edge is 3 cm
Answer:
54
Step-by-step explanation:
Answer:
Step-by-step explanation:
the equation line passes through(-3,0)and (0,3) is : y=ax+b
a is the slope a = (3-0)/(0+3) = 1
so : y= x +b calculate b line passes through(-3,0)and (0,3)
x=0 y=3 : 3 = 0+b so b= 3
this equation is : y= x+3
Answer:
C:
Step-by-step explanation:
Both angles add up to 180°
<BCG + <BFG = 180°
2x+146+4x+238=180
6x+384 = 180°
6x = 180-384
6x = -204
Dividing both sides by 6
x = -34
