Answer:

x is 95 degrees

y is 68.5 degrees

z is 68.5 degrees too

Step-by-step explanation:

180 - 57 - 28 is 95

180 - 43 = 137

137 / 2 = 68.5

Question 6 (5 points)

AleksAgata [21]

Answer:

(26,-2)

Step-by-step explanation:

For any two points on coordinate plane (x1,y1) and ( x2,y2)

coordinate of midpoint is given by (x1+x2)/2 , (y1+y2)/2

Given

(x1,y1) = (-4,-8)

midpoint : (11,-5)

let other point be x2 and y2

therefor by using formula for midpoint coordinate given above we have

midpoint : (11,-5) = (-4+x2)/2 , (-8+y2)/2

Hence point

11 will be equivalent to (-4+x2)/2

11 = (-4+x2)/2

=> 11*2 = -4+x2

=>22 + 4 = x2

=>x2 = 26

similarly

-5 will be equal to (-8+y2)/2

-5 = (-8+y2)/2

=> -5*2 = -8+y2

=> -10 + 8 = y2

=> y2 = -2

Therefore coordinates of other point is (26,-2).

Find what the question asks. 200 points. Will mark brainleist

Note:
The area of a circle with radius r is πr².
An entire circle has a central angle of 360°.

For the sector with radius = (3+4) = 7cm and a central angle of 120°, the area is
$A_{1}= \frac{120}{360}*(49 \pi ) = \frac{49}{3} \pi \, cm^{2}$

For the sector with radius = 3 cm and a central angle of 120°. the area is
$A_{2}= \frac{120}{360} *(9 \pi ) = 3 \pi \, cm^{2}$

The area of the shaded sector (see the figure) is
$A=A_{1}-A_{2} = ( \frac{49}{3} -3) \pi = \frac{40}{3} \pi \, cm^{2}$

Answer: $\frac{40}{3} \pi \, cm^{2}$

I need help I tried to do this question with one C and with two C

OverLord2011 [107]

There are two c's. You must pay attention to capitalization, there's a lowercase c and an uppercase C which represent two different variables. Also, the W is capitalized which could make your answer incorrect if you don't use the same notation.

Solving for small c..

$C = \frac{Wtc}{1,000} \\\\ 1,000C = Wtc \\\\\frac{1,000C}{Wt}= c$

So it's the answer shown in the picture, but it should be a capital W instead of a lowercase w.

Solve for X:

saveliy_v [14]

$- \frac{6}{5} x - 4 = - 46 \\ - \frac{6}{5} x = - 42 \\ - 6x = - 210 \\ x = 35$
Translate the words into math and solve for x. Any questions let me know.
