Answer:
50 degree
Step-by-step explanation:
the angle sum property of the equilateral triangle is =180 degree
since, 52 degree +78 degree +x =180 degree
130 degree + x =180 degree
x= (180-130) degree
<h3> x= 50 degree</h3>

Answer:
see attached
Step-by-step explanation:
Rotation 270° counterclockwise is equivalent to rotation 90° clockwise. The transformation of coordinates is ...
(x, y) ⇒ (y, -x) . . . . . . . rotation 270° CCW
This means the points are moved to ...
A(-2, 1) ⇒ A'(1, 2)
B( 1, 2) ⇒ B'(2, -1)
C(-2, 4) ⇒ C'(4, 2)
The rotated triangle is shown in the attachment. You may notice that A' and B are the same point.
