Sagot :
Step-by-step explanation:
I'm assuming this is an isosceles triangle (cuz those two angles are equal right?)
since it's an Isosceles triangle,
y = 9
Answer:
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
Step-by-step explanation:
im guessing honestly but im pretty sure its 9, sorry if im wrong, have a good day :)
