Question

I need to find x. please show the work aswell

Answer 1

Answer: x = -7

Step-by-step explanation:

The missing angle between the 107 and (4-2x) is 55 due to the vertical angles theorem.

The three angles mentioned add to 180 because they form a straight line.

Here's what the steps would look like:

107+55+(4-2x) = 180

166-2x = 180

-2x = 180-166

-2x = 14

x = 14/(-2)

x = -7
