The image displays a geometrical diagram consisting of two intersecting lines that form an "X" shape. At the center of this intersection is the point marked with the letter "E". The bottom part forms a triangle, with "R" and "T" indicating the two vertices at the base of the triangle. Diagram Description: In the diagram, two straight lines intersect at point E, forming an "X" shape. This intersection creates four sections within the diagram. The base of one of the sections forms a triangle with the letters "R" and "T" indicating the points at the bottom left and right of the triangle respectively. The letter "E" marks the intersection point at the center of the diagram.

The measurement of ∠IVE is 50°, the measurement of ∠VIE is 70°, and the measurement of ∠RET is given by the expression 2x - 10. To solve for the value of x, we need to apply the angle relationships formed at point E. **Problem Statement:** Given: - ∠IVE = 50° - ∠VIE = 70° - ∠RET = 2x - 10 Find the value of x. **Graphical Representation:** The diagram illustrates two intersecting lines TV and RI at point E. The intersection forms four angles, named as follows: ``` V I \ / \ / E / \ / \ T R ``` ### Explanation: 1. **Identify the total measure of angles around point E:** The four angles around point E sum up to 360°. 2. **Sum of opposite angles:** Since TV and RI intersect at E, the pairs of vertical angles are equal. Hence: - ∠IVE + ∠VIE + ∠REV + ∠RET = 360° 3. **Sum of angles on a line:** The angles on a straight line (linear pair) add up to 180°: - ∠VIE + ∠RET = 180° (angles on a straight line TV) 4. **Sum of given angles:** By substituting the given angle values: - 70° + (2x - 10) = 180° - 2x - 10 = 180° - 70° - 2x - 10 = 110° - 2x = 120° - x = 60° ### Conclusion: By solving the equation, we find that \( x = 60 \). So, the value of x that satisfies the given conditions in the geometry problem is 60.
