Answer:
d = 0.39 inch
Step-by-step explanation:
Given data:
Diameter (x) = 5inch
Depth (y) = 4 inch
Distance (d) = ?
Using the parabola formula to find the distance d, we have
x² = 4dy
where x = 5/2 = 2.5 and y = 4
Substituting, we have
2.5² = 4 * d* 4
6.25 = 16d
d = 6.25/16
d = 0.39 inch
You can do basic angle chasing, naming the angles x and the others y. 180-x=y and 360=2x+2y. Then x=x, proving they are vertical angles.
