Find the coordinates of the reflected image. a triangle with vertices  f(–1, 9),  g(–2, 1), and  h(–7, 4) is reflected over the  x-axis.

see explanation

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y ), hence

F(- 1, 9) → F'(- 1, - 9)

G(- 2, 1) → G'(- 2, - 1)

H(- 7, 4) → H'(- 7, - 4)

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
