Two lines intersect. If vertically opposite angles are 4x + 12 and 6x - 18 then what is x?

दो रेखाएं प्रतिच्छेद करती हैं। यदि शीर्षाभिमुख कोण 4x + 12 और 6x - 18 हैं तो x का मान क्या है?

Show answer and explanation
Correct Answer

B. 15 / 15

Explanation

Vertically opposite angles are equal. From 4x + 12 = 6x - 18 we get x = 15.

शीर्षाभिमुख कोण बराबर होते हैं। 4x + 12 = 6x - 18 से x = 15।
