Answer:
58°
Step-by-step explanation:
<h3>Angle sum property of triangle:</h3>The sum of all angles of a triangle is 180°.
x + 69 + 55 + x + 78 = 180
x + x + 69 + 55 + 78 = 180
Combine like terms,
2x + 202 = 180
Subtract 202 from both sides,
2x = 180 - 202
2x = -22
Divide both sides by 2,
x = -22/2
x = -11
∠A = x + 69
= -11 + 69
Applying the translation rule, the coordinates are:
- A'(-1,12).
- B'(3, -3).
- C'(-15, 22).
The translation rule is:
Thus, for the image, the transformation is applied for each coordinate. Then:
