By inspection, the line is y = -x. However, that is not what the question is asking for.

The slope between the two given points is
.. (-2 -2)/(2 -(-2)) = -4/4 = -1

The point-slope form of the equation for the desired point is
.. y -2 = -1(x -(-2))
.. y -2 = -(x +2) . . . . . . . simplified some, still recognizable as point-slope form

AB and DE are chords that intersect at point F inside circle C as shown. If the measure of arc EA= 50 degrees and the measure of

defon

Answer:

Part 1) $m\angle AFE=55^o$

Part 2) $m\angle EFB=125^o$

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.

Note: In this problem the correct measure of arc EA is 40 degrees (see the picture)

$m\angle AFE=\frac{1}{2}(arc\ EA+arc\ DB)$

substitute the given values

$m\angle AFE=\frac{1}{2}(40^o+70^o)=55^o$

Part 2) what is the measure of angle EFB?

we know that

$m\angle AFE+m\angle EFB=180^o$ ---> by supplementary angles (form a linear pair)

substitute the given value

$55^o+m\angle EFB=180^o$

$m\angle EFB=180^o-55^o=125^o$

So I would like help with this question:

madreJ [45]

To find the answer, find the unit rate by dividing 57 by 19. The answer to that is 3. Multiply 48 by 3. That’s how much it costs. Your final answer is 144 cents. I hope this helps!
