Answer:
Look below
Step-by-step explanation:
A.
8 + 9 + 10 = 27
9 + 10 + 11 = 30
10 + 11 + 12 = 33
B. Every answer is divisible by 3, every consecutive answer is also 3 more than the one before it.
C. Yes
19 + 20 + 21 = 60
D. No
8 is not divisible by 3. Also, the closest you can get is 6 (1 + 2 + 3) or 9 (2 + 3 + 4).

Answer:

<h3><u>2775</u> is the right answer.</h3>
x+y=5
-x -x
Equals:
y=-x+5
Now you have:
y=-x+5
x-y=1
Insert -x+5 into y
x-x+5=1
Combine like terms
2x+5=1
Subtract 5.
2x=-4
Divide 2.
Answer: x=-2
The measurement of angle A = 52 ° .
In question we need to find angle A ,
To find angle A using Law of Sines :
Law of Sine : ( a / sin A ) = ( b / sin B ) = ( c / sin C ) where a , b and c are the sides opposite to angle A , B and C resp. of a triangle .
Applying Law of Sines ,
25 / sin A = 28 / sin 62
sin A = ( 25 * sin 62 ) / 28
sin A = 0.7883
Therefore , angle A = 52 ° .
Hence , the measurement of angle A = 52 ° .
