Answer:
angle c
Step-by-step explanation:
angle c is the angle of incidence. It is the angle between the perpendicular ( line that meets the surface at 90 degrees) and the ray that is coming in
<em>only the last figure (i.e figure e) is shaded </em>
The shaded region is a triangle
Area of a triangle
= ½ × b × h
= ½ × 14 × 5
= ½ × 70
= 35yd²
ANSWER

EXPLANATION
Since the parabola has the (0, 0) and the directrix at y=2.
The equation is of the form

where (h,k) is the vertex.
The vertex is half way between the directrix and the focus.
The vertex will be at (0,1)
and is the distance from the vertex to the focus which is 1.

Answer:
x = 23.1
Step-by-step explanation:
The parallel lines make the left segments proportional to the right segments. This lets us write the equation ...
x/14 = 33/20
Multiplying by 14, we get ...
x = 14(33/20) = 7(33/10) = 23.1
