Answer:
108 degrees
Step-by-step explanation:
x + 63 = 8x (vertically opposite angles)
7x = 63
x = 9
8x + angle1 = 180 (sum of angles on a straight line)
8(9) + angle1 = 180
angle1 = 180 - 8(9) = 108

<span>There are 5 boxes, where we have to put given numbers. Addition of 5 odd numbers always gives an odd number result. 30 is an even number. So there is no combination of given numbers which can give you 30 as a result.

We can start by figuring out the axis of symmetry.
y = x² + 12x = x (x + 12)
So roots are x = -12 or 0
Therefore axis of symmetry is x = (-12 + 0) / 2 = -6
We got x-coordinate of vertex. Now plug in x=-6 to solve for y.
y = (-6)² + 12(-6) = 36 - 72 = -36
Therefore vertex is (-6, -36).
