Question

Angle 3 and Angle 6 are alternate interior angles. If angle 3 is (3x-5) degrees and angle 6 is (5x-25), what is the value of x?

Answer 1

• x = 10

Explanation:

Alternate interior angles measure same as per their property:

• m∠3 = m∠6
• 3x - 5 = 5x - 25
• 5x - 3x = 25 - 5
• 2x = 20
• x = 10
