Here's one way to do it.
AB ≅ AC . . . . . . . . . . given
∠BAY ≅ ∠CAY . . . . given
AY ≅ AY . . . . . . . . . . reflexive property
ΔBAY ≅ ΔCAY . . . .. SAS congruence
XY ≅ XY . . . . . . . . . . reflexive property
∠AYB ≅ ∠AYC . . . . CPCTC
BY ≅ CY . . . . . . . . . . CPCTC
ΔXYB ≅ ΔXYC . . . .. SAS congruence
Therefore ...
∠XCY ≅ ∠XBY . . . . CPCTC
The answer is 8

Answer:
11060.83
Step-by-step explanation:
Sum = 10000 + 10250 + 10790 + 9865 + 15350 + 10110
= 66365
No. of days (N) = 6
Arithmetic mean = Sum/ N
= 66365/6
= 11060.83
7/6x=140
since variable x is multiplied by 7/6, find x by multiplying by the inverse of 7/6 which is 6/7.
7/6x × 6/7 = 140 × 6/7
x= 120
