Answer:
if its one of the options and you have the same diagram as me the answer would be 150 the circle adds up to 360 in total so if angle 1 is 100 then angle 2 has to be 80 because a line adds up to 180 since the angle 3 is 30 you just add up 180 and 30 which would be 210 you just subtract that from 360 and you are left with 150
(again only if you have the same diagram as me because i had the same question but with 150 instead or 110)

Answer:
The mode of sunday is 15 is correct
Answer: Sergio's expression is incorrect because he can not simplify 3-6x and Leon's expression is incorrect because he did not multiply 3 by -1.
Step-by-step explanation:
Here, given expression, 9 - (3 - 6x)
After simplifying this we get the following steps,
Step 1) 9 - (3 - 6x) = 9 - 3 +6x ( by removing parenthesis ) -----(1)
Step 2) 9 - (3 - 6x) = 6 + 6x
Step 3) 9 - (3 - 6x) = 6(1 + x) ( because 6 is common in both term of right side)
Since, when Sergio simplified it he wrote 9−(-3x), which is not matching to the above steps. that, is he is incorrect, because in his explanation he wrote -3x after simplifying 3-6x which can not be solved.
Moreover, the expression of Leon is also not matching to any of the above steps,
Thus he is also incorrect because after removing parenthesis he did not multiply 3 by -1 .
