- 10.2n -1
The measure of the three missing angles in the given rhombus are:
x = 122°
z = 58°
y = 122°
<h3>What is a Rhombus?</h3>
A rhombus is a quadrilateral with four interior angles. In a rhombus, the opposite angles are congruent while the adjacent angles are supplementary to each other.
x and 58° are adjacent angles and are therefore supplementary.
x = 180 - 58 = 122°
z = 58° (opposite angles)
y = x = 122° (opposite angles)

The vertex form of the Quadratic equation is y = 
+5. The vertex is (3, 5), which is a maximum point.
<h3>what is a quadratic equation?</h3>
A quadratic equation is an algebraic equation with the power of its variable 2.
it can be written in standard form which is called vertex form or in the general form.
Analysis:
y = 
-6x +14
y = -6x +9 +5
Simplifying this perfect square expression y = -6x +9
y = -3x -3x +9
y = x(x-3) -3(x-3) + 5
y = (x-3)(x-3) +5
y = + 5
In conclusion, the Vertex form of the equation is y = + 5
