Answer:
x = 46
Step-by-step explanation:
Angles in a triangle add up to equal 180
This means that 107 + 27 + x must equal 180
Note that we've just created an equation that we can use to solve for x.
107 + 27 + x = 180
* solve for x *
combine like terms
134 + x = 180
subtract 134 from both sides
134 - 134 + x = 180 - 134
x = 46
