Answer:

?=84

Step-by-step explanation:

From the diagram;

[tex]x+120\degree=180\degree[/tex]

[tex]x=180\degree-120\degree[/tex]

[tex]x=60\degree[/tex]

Also the interior angles of a triangle adds up to 180 degree.

x+y+90=180

60+y+90=180

y==180-150

y=30

Also, we use angles on a straight line to get;

z+114=180

z=180-114

z=66

Again using sum of interior angles of a triangle, we get;

z+y+?=180

66+30+?=180

96+?=180

?=180-96

?=84
