Can you please solve for X

I'm pretty sure that x = 6.

x = 6

Step-by-step explanation:

Since the sum of the angles of a triangle must add up to 180°, we must establish the following formula:

m < 72° + m < 64° + m < (4x + 20)° = 180°

72° + 64° + 4x° +20°  = 180°

Combine like terms:

156° + 4x° = 180°

Subtract 156° from both sides

156° - 156° + 4x = 180° - 156°

4x° = 24°

Divide both sides by 4 to solve for x:

4x°/4 = 24°

x = 6

Double check whether we have the correct value for x by plugging in its value into the equation:

m < 72° + m < 64° + m < (4x + 20)° = 180°

72° + 64° + 4(6)° +20°  = 180°

72° + 64° + 24° +20°  = 180°

180° = 180° (True statement. Therefore, we have the correct value for x).
