it is an eqilateral triangle, 3 equal sides 3 equal angles (60°)

so

2x - 4 = 60

2x = 60 + 4

2x = 64

x = 64 : 2

x = 32 (your answer)

-----------------------

2 * 32 - 4 = 60

the answer is good.

if you want the value of y

60 : 5 = 12

Answer:

32

Step-by-step explanation:

This is an equilateral triangle.  We know this because all 3 sides are marked congruent.

In an equilateral triangle, all three angles are congruent; this means all three angles must be 60° (because 180/3 = 60).

This means we have the equation

2x-4 = 60

Add 4 to each side:

2x-4+4 = 60+4

2x = 64

Divide 2 by each side:

2x/2 = 64/2

x = 32
