Question

find the measure of 'x' for the following figure​

Answer 1

Answer:

let's use exterior angle property of Quadrilateral,

75°+120°+90°+x=> 360°

360°-285°=x

x=75

Answer 2

Answer:

75 degree.

Step-by-step explanation:

180 - 75 = 105 degree ( linear pair )

180 - 120 = 60 degree ( linear pair )

180 - 90 = 90 degree ( linear pair )

105 +60+90 = 255 degree

360 - 255 = 105 degree ( sum of all angles of a quadrilateral is 360 degree )

therefore, X = 180 - 105 = 75 degree.
