Answer:
x ≈ 14.87
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² = 10² + 11² = 100 + 121 = 221 ( take the square root of both sides )
x = ≈ 14.87 ( to the nearest hundredth )

Key word SUM means addition
You can only be able to solve two variables, k and x based on what you input as your question
k= -2x+3
x= (3-k)/2
A' ( 2, 4) and B' ( -4, 0)
A ( -2, 4) and B( 4,0) reflected over the y-axis
the y-coordinate do not change and the x is opposite sign
(x,y) reflected over y-axis (-x, y)

Given:
AC = BC
AC = 40
2AB=AC
Simplify:
BC = 40
2AB = 40
Algebra:
AB = 20
Here's the sides:
Add all of them together:
