The area of a rectangle can be found as:
Answer:
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). ... the line y = x is the point (y, x). The reflection of the point (x,y) across. the line y = -x is the point (-y, -x).

Answer:
65 degrees
Step-by-step explanation:
Since complementary angles are 2 angles that add up to 90 degrees, all you have to do is subtract 25 from 90.
When you do that you get 65.
Example: 90 - 25 = 65
Answer:
∠B = 70 and ∠C = 40
Step-by-step explanation:
The image is not loading for me but with isosceles triangles there will two angles that are the same and one different angle.
All the angles will add up to equal 180 degrees.
In this case the different angle would angle C as the two same lines meet at that point.
From this you can that angle A and B are the same, both 70, so angle C would be:
180 (all the angles of a triangle added together) - 70 - 70 = 40
I'm assuming that x and y are angles B and C as they are not stated so they would be: ∠B = 70 and ∠C = 40.
Here is a diagram to demonstrate this:
