The answer:
the full question is as follow:
<span>Point F is on circle C. What is the length of line segment GF?
12.5 units
15.0 units
17.5 units
20.0 units
according to the image, GF= GC + CF
CF is the radius of the circle, so it is CF =CE = 7.5
all that we want to find is the value of GC
let's consider the triangle GEC. This is a right triangle, so for finding GC, we can apply Pythagorean theorem
that is, GE² + EC² = GC², and from this, we have GC = sqrt(</span>GE² + EC² )
GC = sqrt(10² + 7.5² )=sqrt(56.25)=12.5
<span>
therefore, </span>GF= GC + CF=12.5 + 7.5 = 20.0
the answer is 20.0 units
Answer:
Yes
Step-by-step explanation:
We can use the Pythagorean Theorem to check if this triangle is a right triangle:

Note that
and
are the legs of the triangle and
is the hypotenuse:
Substitute the lengths of the sides into the equation:


Therefore this triangle is a right triangle.
You're right on what you've been doing

=$30,000 + ($2800 * 10 years)
=$30,000 + $28,000
=$58,000 total made in 10 years
Sharla
=$36,000 + ($2000 * 10 years)
=$36,000 + $20,000
=$56,000 total made in 10 years
Difference
=$58,000 - $56,000
=$2,000 difference
ANSWER: Paul made $2,000 more.
Hope this helps! :)
