Step-by-step explanation:
It is 28°
Because both triangles FED and ABC are right (converse of pythagorean theorem)
Also the lengths of the side of the triangle ABC is double the lengths of the side of the other triangle
You calculate the measure of the angle ∠A in triangle ABC which is 28° (by calculation)
This will also be the measure of angle D
I'm not sure if it is right but hopefully it will help you.
Check the picture below.
recall the diameter is twice as long as the radius, thus d = 2r = 38.42 or rounded up to 38.
Answer:

Step-by-step explanation:
There was a population of 108000 in a small town in 2002. Since then, the population has decreased at a rate of 2.5% each year.
Therefore, the population is decreasing at a compound rate of 2.5% each year.
Now, using the formula of compounding we can write if p is the population after t years, then
⇒

Step-by-step explanation:
The standard equation of a parabola with vertex at the origin and and directix x=-p is of the form

Where p is simplify the distance from the origin to the directrix.
That is
