Help I don't know what to choose

Step-by-step explanation:

We know a triangle adds up to 180 so:

75+36+ ? = 180

111+ ? =180

? = 69

To find out x, we know that a straight line adds up to 180 so again:

x +69 = 180

x = 111

let the untitled angle be y.

y+75°+36°=180°[by angle sum property]

y+111°=180°

y=180°-111°

y=69°

x+69°=180°[by linear pair]

x=180°-69

x=111°

y=1/4x-4
