Question

While visiting your friend in the city, you see two roads that intersect as shown. Your triend tells you that the angle between the roads on the west side is 78° and the angle between the roads on the east side is (3x)°. Find the value of x.

Answer 1

Explanation:

180 = 78° + 3x°

78° + 3x° = 180°

3x°= 180° - 78°

3x = 102°

x = 102°/3

Answer 2

Step-by-step explanation: 78 +3x+x=180 deg.

4x=180-78

4x=102/:4

x=25.5 deg
