Respuesta :

The two angles form a straight line and need to equal 180 when added together:


7x + 28 + 33 = 180

Simplify:

7x + 61 = 180

Subtract 61 from both sides

7x = 119

Divide both sides by 7

X = 17


Answer: B.17

the ans is 17°. as both angles added up together would give you 180°. by taking 180°-33°=147°
Then 147°=7x+28
So shift +28 over to the left which becomes 147°-28°=7x
Then 119°=7x
So x=17°
