The longest side in the triangle is opposite to the largest angle of this triangle. If triangle is acute, then all angles are acute. Acute angle has cosine that is positive.
Use cosine theorem to determine the cosine of the largest angle:
where 
is the largest angle.
Then
Since 
then
Divide this inequality by 5:
Note that 
then the smallest possible whole-number value of x is 7.
Answer: correct choice is B
Answer:
4x(4x^3+6x^2-2x+3)
Step-by-step explanation:
Answer:
Always
Step-by-step explanation:
Some people might mistaken it for sometimes, but the part that makes it always is when it says "regular" hexagons.
Similarity is defined by having congruent angles and proportional sides. Regular hexagons will always have internal angles of 60°, meaning that any two regular hexagons will always be similar.
Answer:
<1 <2 and <1 <4
Step-by-step explanation:
A supplementary angle is a straight line with 180 degrees.
Earlier snow depth = 2 feet
later snow depth = 1.6 feet
change
2 - 1.6
0.4 feet
percentage change
(0.4 / 2) * 100
20 %
