Answer:
Step-by-step explanation:
Given that,
The dimensions of an aquarium are 61 cm long, 30.5 cm wide, and 30.5 cm high.
The tank is filled to 80% capacity with water.
We need to find the water needed for this tank.
The volume of cuboid is given by :
As it is filled to 80% capacity, so,
So, of water is needed for this tank.
B
m<G = 55°
m<G = (1/2)[m(arc)LE - m(arc)HF]
m<G = (1/2)[150° - 40°)
m<G = 110°/2
x=6
/AB/=2x+12
/BC/=5x+10
3x+2=5x-10 subtract 2 from both sides
3x=5x-12 subtract 5x from both sides
-2x=-12 divide both sides by -2x
x =6
