Find the value of x.

1. 37°, 2. 53°, 3. 139° and 4. x°
x = [?]°

1 answer

To find the value of \( x \), we need to know the relationship between the given angles (37°, 53°, 139°, and \( x \)). Assuming that these angles are part of a geometrical figure like a triangle or a quadrilateral, there are specific rules we can apply.

  1. If these angles are the angles of a triangle, their sum must equal 180°:

    \[ 37° + 53° + 139° + x = 180° \]

  2. If these angles are the angles of a quadrilateral, their sum must equal 360°:

    \[ 37° + 53° + 139° + x = 360° \]

Let’s calculate both scenarios to determine \( x \):

Scenario 1: Angles in a Triangle

\[ 37° + 53° + 139° + x = 180° \] \[ 229° + x = 180° \] \[ x = 180° - 229° \] \[ x = -49° \quad (\text{Not possible in a triangle}) \]

Scenario 2: Angles in a Quadrilateral

\[ 37° + 53° + 139° + x = 360° \] \[ 229° + x = 360° \] \[ x = 360° - 229° \] \[ x = 131° \]

Thus, if the angles are part of a quadrilateral, \( x = 131° \).

Therefore, the value of \( x \) is: \[ \boxed{131°} \]
