Math Problem Statement

Find the value of x, where m∠2 = x + 58, and the triangle's angles include 65° and 2°.

Solution

The problem involves finding the value of xx, given that m2=x+58m\angle 2 = x + 58 and the provided triangle diagram.

Step 1: Analyze the Triangle

The triangle has the following:

  • One angle labeled 6565^\circ.
  • m2=x+58m\angle 2 = x + 58, indicating this is another angle of the triangle.
  • The third angle (top-left) is marked as 22^\circ.

Step 2: Use the Triangle Angle Sum Property

The sum of the interior angles of a triangle is always 180180^\circ. Therefore: 65+m2+2=18065^\circ + m\angle 2 + 2^\circ = 180^\circ

Step 3: Solve for m2m\angle 2

Substituting m2=x+58m\angle 2 = x + 58: 65+(x+58)+2=18065^\circ + (x + 58) + 2^\circ = 180^\circ

Simplify: 125+x=180125^\circ + x = 180^\circ

x=180125x = 180^\circ - 125^\circ

x=55x = 55^\circ
