Answer:

Step-by-step explanation:

Answer:
63+ 2x- 17 = 180 degree
or, 2x+46=180degree
or, 2x=180-46=134degree
or, x = 134÷2=67 degree ans.
It would be the first one because if you do 4^2+4^2 it does NOT equal 32 it equals a even greater number. So the first one is not a right triangle
Add the common difference to a term to get the next term.
-10
-10 + (-2) = -12
-12 + (-2) = -14
etc.
The sequence is
-10, -12, -14, -16, -18, -20, -22, -24, -26, -28
