Answer:
Anton's definition is not valid.
Step-by-step explanation:
We have been given that Anton defines an acute angle as an angle that is not obtuse. We are asked to find whether Anton's definition is valid or not.
We know that an angle is known as acute angle whose measure is greater than 0 and less than 90 degrees.
We also know that an angle is known as obtuse angle whose measure is greater than 90 degrees and less than 180 degrees.
We know that a right triangle is neither acute nor obtuse. Since Anton hasn't mentioned a right triangle to his definition, therefore, his definition is not valid.
Answer:
<u>The function f(x)=a(x-h)² + k is the parabola with vertex:</u>
If the vertex is in the second quadrant, the h < 0 and k > 0
It can open up or down, so a ≠0, it opens up if a > 0, opens down if a < 0
The axis of symmetry is the line parallel to y-axis and passing through the vertex, so it would be the line:
<u>Now let's assume h = -5, k = 2, a = 1, then our function is:</u>
The graph is attached and it opens up as a = 1 > 0
<u>The line of symmetry is </u>

Answer:
D
Step-by-step explanation:
The sum the areas of Square N and Square L is equal to the areas of Square K
The two triangles are isosceles.
Both triangles have the equals sides equal to 6
Both ∠ 1 and the ∠2 are the opposite angles to the different side of their respective triangles.
The opposite side to ∠ 1 is shorter than the opposite side to ∠ 2, which implies that ∠1 is less than ∠2.
Then the inequality that relates those angles is
∠1 < ∠2
