<u><em>Reflection of point U across y-axis = (1, -5)</em></u>

why . . .

reflection across y-axis means to take the negative of the x-value, and since point U has coordinates (-1, -5), the negative of -1 is 1, then the reflected coordinate must be (1, -5)

Answer:

B. (1,-5)

Step-by-step explanation:

We have been coordinates of some points on coordinate plane. We are asked to find the reflection image of U across the y-axis.

We know that after reflecting a point across y-axis, the y-coordinate of point remains same, while x-coordinate changes to its opposite sign.

We can see that coordinates of point U are (-1,-5). After the reflection across y-axis the y-coordinate will remain same that is -5, while x-coordinate will be opposite of -1 that is -(-1)=1

Therefore, the coordinates of point U after reflection across y-axis would be (1,-5) and option B is the correct choice.

Find the distance from point C to point D.
sineoko [7]

The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. The distance from point C to point D is 258.8 meters.

<h3>What is Tangent (Tanθ)?</h3>

The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. it is given as,

\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The base is the adjacent smaller side of the angle θ.

The distance from point C to D is equal to the distance from point A to B. Therefore, the height of the building can be written as,

Tan(25°) = AB / BC

Tan(25°) × 555 m = AB

AB = 258.8 meters

Hence, the distance from point C to point D is 258.8 meters.
