Question

find the value of x. x = ?° 51° (3x)°

Explanation:

Step1: Identify Vertical Angles

The angle of \(51^\circ\) and the angle of \((3x)^\circ\) are vertical angles, so they are equal.
\[
3x = 51
\]

Step2: Solve for \(x\)

Divide both sides of the equation by 3.
\[
x=\frac{51}{3} = 17
\]

Answer:

\(x = 17\)
