Question

Find the value of x that makes line m ll n

Answer 1

Answer:

See below ↓

Step-by-step explanation:

14.

• Between two lines m ║ n, the ∦ cuts through them forming two angles
• As it forms a line, the sum of the angles is 180°
• 3x + 47 + x + 7 = 180
• 4x + 54 = 180
• 4x = 126
• x = 126/4 = 63/2 = 31.5

15.

• Alternate exterior angles on a transversal are equal
• 5x = 2x + 78
• 3x = 78
• x = 26
