Answer:

The answer is 100*

Step-by-step explanation:

The three measures of the angles add up to make a strait line (180*)

Subtract the value of the two given angles from the total of 180 to get the difference

180 (total) - 50 (m<A) - 30 (m<B) = 100 (Answer)

X= 100 as it is a obtuse obtuse angel

The answer is 100
