Question

s
3x - 13
r
2x
t

Explanation:

1. Explanation:

• Assume that in the triangle, the two - equal angles imply that the sides opposite to them are equal. If the angles at the base of the triangle (the angles adjacent to the non - equal sides) are equal, then the triangle is isosceles and the two non - base sides are equal. So, we set up the equation based on the equality of the two sides of the isosceles triangle.
• We set \(3x−13 = 2x\) (since the sides opposite the equal angles are equal).
• Step 1: Isolate the variable \(x\) terms on one side
• Subtract \(2x\) from both sides of the equation \(3x−13 = 2x\).
• \(3x−2x−13=2x - 2x\).
• \(x−13 = 0\).
• Step 2: Solve for \(x\)
• Add 13 to both sides of the equation \(x−13 = 0\).
• \(x=13\).
