Math Problem Statement

Find the value of x

Find the value of x.

Solution

To find the value of xx, let’s analyze the diagram provided.

This is a problem involving angles around a point, and the sum of these angles should equal 360360^\circ.

In the diagram, we have three given angles:

  1. xx
  2. 3434^\circ
  3. 3x3x
  4. 2222^\circ

Setting up the equation, we can add these angles and set the sum equal to 360360^\circ:

x+34+3x+22=360x + 34^\circ + 3x + 22^\circ = 360^\circ

Now, combine like terms:

4x+56=3604x + 56^\circ = 360^\circ

Subtract 5656^\circ from both sides:

4x=3044x = 304^\circ

Now, divide by 4:

x=76x = 76^\circ

Answer:

The value of xx is 7676^\circ.

Would you like further details or have any questions?

Here are some related questions for practice:

  1. What would the value of xx be if one of the other angles was changed?
  2. How would you approach this problem if it were an equation involving supplementary angles?
  3. What if there were four angles around the point, and their sum was different?
  4. How can this method be applied to find unknown angles in polygons?
  5. Why does the sum of angles around a point equal 360360^\circ?

Tip: When solving for unknowns in angle problems, always look for the sum of angles rules (e.g., around a point, in a triangle) to set up your equation.
