Question

Find the value of x in the figure below.
Assume that the lines are parallel.

Answer 1

x = 30 degrees

Explanation:

Since the lines are parallel, these angles can be seen as vertical angles, which are always the same as their opposite. Therefore,

75 = 2x + 15

To solve this, you would subtract 15 from both sides, getting you closer to finding x.

75 = 2x + 15

-15 - 15

60 = 2x

Lastly, you would divide both sides to get your value for x.

60 = 2x

/2 /2

30 = x
