No she is not correct she needs to go back to school and learn math
Answer:
if we have the point (x, y), a reflection over the x-axis give us the point (x, -y)
if we have the point (x, y), a reflection over the y-axis give us the point (-x, y)
if we have the point (x, y), a reflection across both axes give us the point (-x, -y)
1. (2, -3) → (-2, -3) ------- reflection across the y-axis
2. (2, -3) → (-3, 2) -------- not a reflection
3. (2, -3) → (-2, 3) ------ reflection across both axes
4. (2, -3) → (2, 3) ----- reflection across the x-axis
Answer:
a = 70°
b = 80°
Step-by-step explanation:
Angles on a straight line add up to 180°
⇒ a + 110 = 180
⇒ a = 180 - 110
⇒ a = 70°
The sum of the interior angles of a quadrilateral is 360°
⇒ a + b + 130 + 80 = 360
⇒ 70 + b + 130 + 80 = 360
⇒ b + 280 = 360
⇒ b = 360 - 280
⇒ b = 80°
