Answer:
If angle 2 = 110 then angle 4 = 110
360 = 110 + 110 + x
Angle 1 + Angle 3 = 140
Since vertical angles are equal, then Angle 1 = 140 / 2 = 70 degrees
Step-by-step explanation:
I believe it is a because I had a question just like that in 8th grade
F ( x ) = - 2 x² + 12 x + 5 = - 2 ( x² - 6 x ) + 5 = - 2 ( x² - 6 x + 9 - 9 ) + 5 =
- 2 ( x² - 6 x + 9 ) + 18 + 5 = - 2 ( x - 3 )² + 23
f ( x ) = a ( x - k )² + h ( the vertex form ), k = 3, h = 23.
a = - 2 < 0, that means the vertex coordinates ( 3, 23 ) represents a maximum.
