We are given that the angle a is the right angle. So let
us work from this.
ab = 12 (the vertical side of the triangle)
bc = 13 (which if drawn can be clearly observed to be the
hypotenuse) = the side opposite to angle a
ca = 5 (the horizontal side of the triangle)
Since we are to find for the cosine ratio of angle c or
angle θ, therefore:
cos θ = adjacent side / hypotenuse
cos θ = ca / bc
cos θ = 5 / 13
Check out the attached image below for the illustration
of the triangle.
The Pythagorean theorem states that a² + b²= c². this theorem only works with RIGHT TRIANGLES, and thats all.
i don't think dilations has a formula, unless you count the scale factor as its formula.

Answer:
2x + y = 10 2 x + y = 10 Subtract 2x 2 x from both sides of the equation. y = 10− 2x y = 10 - 2 x Rewrite in slope-intercept form.
