Answer:

x = -6.

Step-by-step explanation:

First thing to notice is that this is the third angle in a triangle, and all 3 angles have to equal 180.

Subtract 75 and 40 from 180 to get the missing angles value.

180 - 75 - 40 = 65

So now we know the missing angle has to be 65, or can be written as:

x + 71 = 65.

To solve this, just subtract 71 from both sides.

x = -6.
