Answer:
A. x = 68, y = 75
Step-by-step explanation:
So you see how those three angles all make a straight line? that's called complementary, where it all makes 180˚.
So, you know that...
(x-1)˚ + 40˚ + (y-2)˚ = 180˚
I'm not sure what that 74˚ is about, but what I would do is plug in the options until you get 180 degrees.
In this case, its the first option, A.
(68-1)˚ + 40˚ + (75-20)˚ = 180˚, which is true! so its A.

Answer:
D. 1.2
Step-by-step explanation:
The sum of an arithmetic sequence is the product of the average term value and the number of terms.
The average term is often computed by averaging the first and last terms of the sequence. It can also be computed by averaging the middle two terms of the sequence (when there are an even number of terms, as here).
We are given a_13 is 1.9. We know that a_12 is 3.7 less, so is -1.8. Then the average of these two middle terms is ...
... (-1.8 + 1.9)/2 = 0.05
The product of this value and the number of terms (24) is ...
... 24·0.05 = 1.2 . . . . . the sum of 24 terms of the sequence
The answer is the last one 300
