Z would be 3 because 10*3 is 30 and 30-2 would be 28 :)
Answer:
y=-x-2*-3
Step-by-step explanation:
Im not sure but since the angle you have is 52 and this is an isosceles triangle so you will do 180-52 over 2 to get the other 2 angles which will be 64 each and you want the exterior angle which is 180 aswell so you will do 180-64 which will be 116
9/8 that’s what I got but you can reduce it
