solve for x.\n\nx = \n\nsave answer

Explanation:

Step1: Identify angle - relationship

The angles $(3x + 25)^{\circ}$ and $(4x-10)^{\circ}$ are vertical angles. Vertical angles are equal. So, we set up the equation $3x + 25=4x - 10$.

Step2: Solve the equation for x

Subtract $3x$ from both sides: $3x+25-3x=4x - 10-3x$ $25=x - 10$. Then add 10 to both sides: $25 + 10=x-10 + 10$ $x=35$.

Answer:

$35$
