Yes, because if two angles of a triangle are equal, then the third angle must also be equal, because angles of a triangle always add to make 180°.
Vertex form formula: y = a(x-h)^2 +k, with vertex (h,k)
There are multiple ways to find the vertex. One way is to find the roots and then find the x value exactly in between them, because this parabola is symmetrical.
0 = (x - 3)(x + 2), so x = 3 and -2. The point directly in the middle is x = 1/2 = h
To find the y value of the vertex, plug in 1/2 to the equation.
(1/2)^2 - 2(1/2) + 5 = 4.25 = k
y = (x - 0.5)^2 + 4.25
11.11111111
you can round your answer
divide 27 by 9 you get 3
divide hundred by 9
you get your answer
17 because 100 - 55 = 45 14/45%= 31 31 times 55%= 17
