Answer:
okay so the answer is 70°
Step-by-step explanation:
the triangle has two sides equal meaning its a scalene triangle. now bases scalene triangles have two angles equal. hence sum of angles in the triangle sum up to 180° please. rate. me brainliest. if I'm. right
Dilating the triangle ABC would create another triangle whose size is different from the triangle ABC
<h3>How to dilate the triangle?</h3>From the complete question, we have the following coordinates:
The dilation rule across the center P is:
(x, y) --> (1/3x – 1, 1/3y + 4)
So, the coordinates of the image of the triangle are:
A' = (-1/3 * 4 – 1, 1/3 * 5 + 4)
A' = (-7/3, 17/3)
B' = (1/3 * 7 – 1, -1/3 * 7 + 4)
B' = (4/3, 5/3)
C' = (-1/3 * 2 – 1, 1/3 * 2 + 4)
C' = (-5/3, 14/3)
From the above computation, the coordinates of the new triangle is:
A' = (-7/3, 17/3)
B' = (4/3, 5/3)
C' = (-5/3, 14/3)

Answer:
Step-by-step explanation:
From the figure, it is downward parabola of the form
The parabola has its vertex at
Distance between parabola vertex and its directrix is 1 unit.
So, the value of a is 1
Hence, the equation of parabola is
