Answer:
answer below
Step-by-step explanation:
∠3 = 76°
∠1 = ∠3 = 76° (vertical angle)
∠2 = 180 - ∠1 = 180° - 76° = 104° (supplementary adjacent angle)
∠4 = ∠2 = 104° (vertical angle)
X-2.13=5.3 x= 5.3 + 2.13 x = 7.43
+2.13
Process:
Start by isolating the variable by itself, in this case we add 2.13 to the -2.13 as whatever we do to one side of the equation we do to the other hence we add 2.13 to 5.3 which will become x = 7.43 and we can verify our answer by substituting our answer for x
7.43 - 2.13 = 5.3
Answer:

Step-by-step explanation:
To work out x is easy as they are corresponding angles x will also equal 50
however to work out y you just need to minus 180 and 50 to give 130

No because the perfect trinomial has a square as the third term and the middle term is a multiple of 2.
