Angle c is a right angle, symbolized by the box drawn on top of it.
Angle c = 90
Angle a = 28
If the sum of the measures of the angles of a triangle is 180, then all you need to do is add the measure of the known angles and subtract the sum from 180.
<h2><u><em>
Angle b = 62</em></u></h2>
Standard form for a parabola:
( x - h )² = 4 p ( y - k )
Vertex: ( h, k ) = ( -4, 2 )
Displacement from vertex to focus:
p = 2/8 = 1/4
( x + 4 )² = 4 · 1/4 ( y - 2 )
y = ( x + 4 )² + 2
or general form:
x² + 8 x - y + 18 = 0
24 because it is the most common multiple of the two.
