Given that x^2-8x+9=(x-a)^2-b for all values of x, a) find the value of a and b.

b) Hence write down the coordinates of the turning point on the graph of y = x^2-8x+9

constants mean the stopped points or the points on a graph that nothing is changing, hope this

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
