Find the value of x that makes line m ll n

guapka [62]

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
