Two lines intersect. If vertically opposite angles are 3x + 10 and 5x - 30 then what is x?

दो रेखाएं प्रतिच्छेद करती हैं। यदि शीर्षाभिमुख कोण 3x + 10 और 5x - 30 हैं तो x का मान क्या है?

Show answer and explanation
Correct Answer

B. 20 / 20

Explanation

Vertically opposite angles are equal. From 3x + 10 = 5x - 30 we get x = 20.

शीर्षाभिमुख कोण बराबर होते हैं। 3x + 10 = 5x - 30 से x = 20।
