Answer 1

Answer:

sorry babe i dont know

Answer 2

Answer:

Step-by-step explanation:

see in 1.) the exterior angle measures 130 so inner - 90+x=130 so answer will be 40 so x is equals to 40 and the reason is that inner two angles add together to make one exterior

in 2.) inner two opposite angles are already given so x measures 70+80= 150 so x = 150 and to find y we know that all angles of a triangle measure 180 so 70+80+y = 180 and y = 20

3.) we subtract x₃ from 8x₃ so 7x₃

ans is 7x₃+3x+11x₂+8

and 4 will be done in the same way
