Answer:
120
Step-by-step explanation:
it is an obtuse angle
The answer is:
The missing angle "x" is equal to 130°.
We need to remember that the sum of all of the angles of any polygon will be all equal to 360°.
So, we are given the following exterior angles:
Now, if the sum of all the exterior angles is equal to 360°, we can use it to calculate "x", so:
Hence, the missing angle "x" is equal to 130°.
