PLEASEE HELP the triangle stu is graphed at s(-2, 1) t(-5, 3) u(1,4). triangle stu is reflected over the y-axis to create triangle s't'u' and then translated by the rule (x, y) -> (x+1, y-2) to create s"t"u" write the coordinates for triangle s't'u' and s"t"u". express your answer as an ordered pair.

The given given transformation are applied to the vertex point of each preimage to obtain the coordinates of the image

Reason:

The given vertices of the triangle Δstu are;

s(-2, 1), t(-5, 3), u(1, 4)

The given transformations are;

1) Reflection across the y-axis to create Δs't'u'

2) Translation by the rule (x, y) (x + 1, y - 2), to s''t''u''

Required:

To write the coordinates for triangle s't'u' and s''t''u''

Solution:

The image of the point (x, y) following a ,  is (-x, y)

Therefore, we have;

s(-2, 1) s'(2, 1)

t(-5, 3) t'(5, 3)

u(1, 4) u'(-1, 4)

The transformation (x + 1 , y - 2), gives;

(x + 1 , y - 2) =

Therefore, we have;

s'(2, 1) s''(2 + 1, 1 - 2) = s''(3, -1)

t'(5, 3) t''(5 + 1, 3 - 2) = t''(6, 1)

u'(-1, 4) u''(-1 + 1, 4 - 2) = u''(0, 2)

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
