Answer:
6.89
Step-by-step explanation:
(6.89+14.52)+(-14.52)
=6.89+14.52-14.52 First take away the parenthesis
=6.89 The positive and negative 14.52 cancel out
Answer:
segment GH ≅ segment FH because the tangents that create the segment FG share a common endpoint.
Step-by-step explanation:
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1) what is the measure of angle AFE
we know that
The measure of the interior angle is the semisum of the arches that comprise it and its opposite.
<u>Note:</u> In this problem the correct measure of arc EA is 40 degrees (see the picture)
so
substitute the given values
Part 2) what is the measure of angle EFB?
we know that
---> by supplementary angles (form a linear pair)
so
substitute the given value
First, we calculate the radius of the circle.
radius=diameter / 2
radius=44 ft / 2=22 ft.
Second; we calculate the area of a circle.
area of a circle=πr²
area of a circle=π(22 ft)²=484π ft²
Remember: 22²=22 * 22 =484
Answer: B) 484π ft²

Answer:
v = 39; w = 47; x = 94; y = 39; z = 47
Step-by-step explanation:
The figure shows v° and 51° are complementary, as are z° and 43°.
v° = 90° -51° = 39°
z° = 90° -43° = 47°
Vertical angles are congruent.
y° = v° = 39°
w° = z° = 47°
And the angle x° is a vertical angle with the sum of 51° and 43°.
x° = 43° +51° = 94°
