1- FM is 3
we know that FM and FG are radius of the circle. so:
FM =FG
so if we find FG by Pythagorean theorem, we find FM, too
FL (hypotenuse) is 5
HL is 8. GL is half of HL. so GL is 4
now we can use Pythagorean theorem to find FG
2- x is 40
BAD is half of m DB
ADB is half of m AB
so BAD is 50
and ADB is 90
Then ABD will be:
good luck

Answer:
After 15 years, the area will be of 775.3 km²
Step-by-step explanation:
The equation for the area of the forest after t years has the following format.
In which A(0) is the initial area and r is the yearly decrease rate.
A certain forest covers an area of 2600 km2.
This means that
Suppose that each year this area decreases by 7.75%.
This means that
So
What will the area be like after 15 years?
This is
After 15 years, the area will be of 775.3 km²
