Question

The two horizontal lines in the diagram are parallel. The value of x is?

Answer 1

x = 130

Explanation:

Since the lines are parallel

The right side angle in the lower triangle = 60° ( alternate angles )

The external angle of a triangle is equal to the sum of the 2 opposite interior angles, thus

x = 70 + 60 = 130

Answer 2

explanation: if you were to flip the line and triangle down, you could see that 60° is in the left corner and 120° and 60° equal 180°

final answer: 120°
