<u>Adjacent angles on a straight line = 180:</u>
x + x + 48 = 180
2x + 48 = 180
2x = 132
x = 66°
<u>Sum of angles in a triangle = 180:</u>
z = 180 - 66 - 90
z = 24°
Answer: z = 24°

According to the vertex and the directrix of the given parabola, the equation is:
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:
In which a is the leading coefficient.
The directrix is at y = k + 4a.
In this problem, the vertex is (1,4), hence:
The directrix is at y = 7, hence:
Hence, the equation is:

Convert 864 square inches to square feet.
1 square inch = 0.00694444444 square feet
Multiply 864 to it.
864 * 0.00694444444 = 6
Now multiply 8 to find out how many pieces of glass you need to use.
8 * 6 = 48
So you need 48 pieces of glass to make a window that is 864 square inches.
