4 Find The Value Of X 860 123 class=

Sagot :

180 - 86 = 94° (angles on a straight line add up to 180°)

180 - 123 = 57° (angles on a straight line add up to 180°)

94 + 57 = 151° ( sum of opposite interior angles of a triangle is equal to exterior angle of the other)


OR

97 + 54 = 151

180 - 151 = 29° (angles in a triangle add to 180°)

190 - 129 = 151° (angles on a straight line add to 180°)

Hope that helps!
