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.

<u>Note:</u> 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

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

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

I hated probability in middle school. I'm not 100% sure but I would go with the 3rd answer choice, 3/100.

Sandra saves 10% of her salary for retirement. This year her salary was $2,000 more than in the previous

You should divide 48,000 by 12 which is 4000+ 2000=6000
So it should be $6000
Hope this is right I’m not 100%

I am having trouble with this problem....

There 2 angles are corresponding angles, in which the angle measurements would have the same degree.

Set the two angles equal to each other, and solve for x.

7x - 1 = 8x - 14

Isolate the x. Subtract 8x from both sides, and add 1 to both sides

7x (-8x) - 1 (+1) = -14 (+1)

7x - 8x = -14 + 1

-x = -13

Isolate the x. Divide -1 from both sides

(-x)/-1 = (-13)/-1

x = -13/-1

x = 13

13 is your answer for x.
