Step-by-step explanation:
every triangle inscribed into a circle with the baseline being a diameter of the circle must be a right-angled triangle.
therefore,
angle XVY = 90°.
for VY we can use Pythagoras
c² = a² + b²
with c being the Hypotenuse (the line opposite of the 90° angle, in our case XY).
XY = 2×ZY = 2×17 = 34.
so,
34² = 30² + VY²
VY² = 34² - 30² = 1156 - 900 = 256
VY = 16
Answer:
using Pythagoras theorem x=32.7
ANSWER
The other zero is

EXPLANATION
The axis of symmetry serves as the midpoint of the two zeroes.
We were given that the axis of symmetry of the quadratic equation is

We were also given that, one of the zeroes of the quadratic equation is

Let the other zero of the quadratic equation be

,then, we apply the midpoint formula to find the value of

Since it is the x-values of the intercepts that gives the solution, we use only the x-value part of the midpoint formula which is given by,

We substitute to obtain,

We multiply through by 2 to get,

This implies that,
