Find the image of (3,5) reflected across the x-axis

The image of (3,5) is reflected across the x-axis. We will solve by the concept of a graph.

Given:

x=3

y=5 as coordinates in the graph.

To find the image in general, when reflects a single point across the abscissa( x-axis), if coordinates of the pre-image are (x , y), then we can say that the coordinate of the reflection of the image is (x , -y).

Here, the x-coordinate remains the same and the y-coordinate was 5, above the x-axis. we will check the image only for ordinate i.e. y which is y=5

so for the image when refect it will become -5, which will lie below the x-axis.

Therefore, The image of (3,5) reflected across the x-axis will be (3, -5)

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

the answer would be 44.79
