Suppose a triangle has sides a, b, and c, and the angle opposite the side of length b is obtuse. What must be true?
1 answer:
Answer: D.
Step-by-step explanation:
In the given figure, we have an obtuse triangle which has sides a, b, and c, and the angle opposite the side of length b is obtuse.
∵ In a triangle, the side opposite to the largest angle is largest.
Thus, the largest side in then given obtuse triangle= c
The Pythagorean inequalities theorem says that If a triangle is obtuse than the square of the largest side is greater than the sum of square of other two sides.
Therefore, we have

Answer: The mass of the object is 10 kg
Step-by-step explanation:
According to Newton's second law of motion, the force applied to an object with mass
is directly proportional to its acceleration
:
(1)
If we isolate :
(2) This means the acceleration of the object varies inversely with its mass
Now, we are given the following data to calculate a constant force using (1):
(3)
(4)
(5)
If we apply this same force calulated in (4) in another object with an acceleration of , its mass
will be:
(6)
(7)
Finding :
This is the mass of the object
