Answer:
Step-by-step explanation:
Given:
Focus point = (-5, -4)
Vertex point = (-5, -3)
We need to find the equation for the parabola.
Solution:
Since the x-coordinates of the vertex and focus are the same,
so this is a regular vertical parabola, where the x part is squared. Since the vertex is above the focus, this is a right-side down parabola and p is negative.
The vertex of this parabola is at (h, k) and the focus is at (h, k + p). So, directrix is y = k - p.
Substitute y = -4 and k = -3.
So the standard form of the parabola is written as.
Substitute vertex (h, k) = (-5, -3) and p = -1 in the above standard form of the parabola.
So the standard form of the parabola is written as.
Therefore, equation for the parabola with focus at (-5,-4) and vertex at (-5,-3)
The angles 150°, 20°, and 20° are not the angles of the triangle.
The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
We know that the interior angles of the triangle are the supplementary angles which means the aggregation of the angle results in 180 degrees.
The angles are 150°, 20°, and 20°.
Check whether these angles are the angles of a triangle or NOT. If the sum of these angles is 180 degrees, then they are the angles of triangle.
⇒ 150° + 20° + 20°
⇒ 190°
The angles 150°, 20°, and 20° are not the angles of the triangle.
