Answer:
NB = b
NC = c
Step-by-step explanation:
A "quick and dirty" proof could be this:
M is the midpoint of AN; M is the midpoint of BC . . . . givenABNC is a parallelogram . . . . diagonals AN and BC have the same midpoint (M)*NB = AC = b; NC = AB = c . . . . opposite sides of a parallelogram are congruent.__
More formally, we might prove it like this:
MC = MB . . . . definition of medianMA = MN, AC = b, AB = c . . . . given∠CMA ≅ ∠BMN . . . . vertical angles are congruentΔCMA ≅ ΔBMN . . . . SAS congruence postulateAC ≅ NB . . . . CPCTCNB = b . . . . substitution property of equality/congruence∠CMN ≅ ∠ BMA . . . . vertical angles are congruentΔCMN ≅ ΔBMA . . . . SAS congruence postulateAB ≅ NC . . . . CPCTCNC = c . . . . substitution property of equality_____
* The proof is "dirty" only in that the theorem "if the midpoints of the diagonals of a quadrilateral are coincident, then that quadrilateral is a parallelogram" is not one usually available to cite in proofs. The "more formal" proof here essentially proves that the quadrilateral is a parallelogram.
a water tank already contained 24 gallons of water before a pump was switched to fill it. the pump started at 10:00 am and by 10:30 am the tank contained 40 gallons of water. by 1:00 pm the tank contained 120 gallons of water. assuming the pump is filling the tank at the same rate without interruption, when will the tank contain 200 gallons?
Answer: ✧༺♥༻∞3:30pm∞༺♥༻✧
Step-by-step explanation: ☆○o。200-24=176
176 divided by 16 (16 is how many gallons was added in half an hour)= 11. 11 divided by 2= 5.5 hours. 10:00am + 5.5 hours= 3:30pm. Hope this helped! ♡ 。o○☆

In a museum there is a sculpture in the shape of a cylinder. The cylinder has a diameter of 10 feet and a height of h feet.
Which equation can be used to find V, the volume of the cylinder in cubic feet?
Answer Choices:
A.) ∨= π (5)²h
B.) ∨= π (5h)²
C.) ∨= π (10)² h
D.) ∨= π (10h)²
Answer: A
Step-by-step explanation:
The diameter is 10 ft and to get r you divide 10 by 2 to get 5. Then square the radius and multiply by h.

Obtuse Triangle
Step-by-step explanation:
The answers to number 1 for each triangle are solved exactly how they are written :).
The number 2s of each triangle are just numbers squared. 15 squared is 225. 18 squared is 324.
Triangle 1 is a right triangle because the angle is a right angle and the triangle can be solved perfectly using the Pythagorean Theorem.
Triangle 2 is an Obtuse Triangle because one side has a way larger angle than the other two angles.
