Question

I need to find the value of y. how do I do that?​

Answer 1

y is 9, the sum of all angles is 180 degrees, so you take 180/9 and thats 20 but you can see 9 and y is about the same length so y is 9 and the other side is 11

Explanation:

im guessing honestly but im pretty sure its 9, sorry if im wrong, have a good day :)

Answer 2

Explanation:

I'm assuming this is an isosceles triangle (cuz those two angles are equal right?)

since it's an Isosceles triangle,

y = 9
