Step-by-step explanation:
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.
Answer:
Sum of 2 no. 120
Let second no. be x
Therefore, first no. =x+5
Therrfore,third no. =3x
Thetefore,x+5+x+3x=120
5x+5=120
5x=115
x=23.
Therefore, 1st no.=28
Second=23
and third=69
Answer:
-2
Step-by-step explanation:
rise over run is 2/1 and y is decreasing as x is increasing so its negative
Answer:
60
Step-by-step explanation:
We are given the triangles are congruent, that means the angles are the same measurement
<A = <X
<B = <Y
<C = <Z
We know A = 50 so X = 50
We know <Y = 70 so < B = 70
The three angles of a triangle add to 180
<A + <B + <C = 180
Substituting into the equation
50 + 70 + <C = 180
Combining like terms
120 + <C =180
Subtracting 120 from each side
120-120 +<C =180-120
<C = 60
