B
>C
?
D
1>) 170°
1) 30°
1) 25°
1) 180°

If we know that the WHOLE angle added is 105 and only part is 75 you need to subtract the whole angle and subtract from part of the whole angle.

105-75=30. You get 30 And that’s you answer!

Step-by-step explanation:

2QR = FH

2(x + 22) = x + 33

2x + 44 = x + 33

-x -x

x + 44 = 33

-44 -44

x = -11
