Question

Determine the measure of the missing angle

50 degrees
60 degrees
180 degrees
360 degrees

Answer 1

Answer: 60

Explanation: Every polygon adds up to 360.
What you can do is 360 - 120 - 95 - 85 = 60.

OR

120 + 95 + 85 = 300
360 - 300 = 60.

Answer 2

x = 60

Explanation:

Let x = ?

120 + 95 +85 +x =360

x +300 =360

x = 360-300

x = 60
