Triangles ABC and AFD are congruent equilateral triangles. Find x and y.

x = 7, y = 27

Step-by-step explanation:

An equilateral triangle means all sides are equal, so you can say that

x + 4 = 2x - 3

Solve

4 = x - 3

7 = x

Because the triangles are equilateral, the angles must be 60 degrees.

2y + 6 = 60

Solve

2y = 54

y = 27

$59 is the fixed cost of the phone and that will never change. This means it won't have a variable attached and will simply be added on to the cost

$39 is how much Jonathans will pay per month. This will change based on how many months pass. This will have the variable attached.

This means the formula is:

59 + 39m

Let me know if this made sense!
