Question

vertical angles
value of x\tresult
(3x - 12)°
75°

Explanation:

Step1: Recall vertical - angle property

Vertical angles are equal. So $3x−12 = 75$.

Step2: Solve the equation for x

Add 12 to both sides: $3x=75 + 12$, so $3x=87$.

Step3: Isolate x

Divide both sides by 3: $x=\frac{87}{3}=29$.

Answer:

$x = 29$
