Answer:
Step-by-step explanation:
We require 2 equations with the repeating decimal after the decimal points.
let x = 2.3333... → (1) ← multiply both sides by 10
10x = 23.333..... → (2)
Subtract (1) from (2), thus eliminating the repeating decimal
9x = 21 ( divide both sides by 9 )
x = =
14x-5=65 ( vertically opposite angles)
14x=65+5
14x=70
x=5
z= 180-65= 115
