Answer:

angle 2 is 43 as the opposite side of the angle is always equal angle 1 and 3 are:

step 1

43+43=86

step 2

360-86=274

step 3

274÷4=68.5

we subtracted 86 with 360 because 360 is the sum of all the angles we then divided the answer by 2 as we were suppose to find two angles angle 1 and 3 are opposite angles so they both will be same

hope this information helps u :)

Answer:

see explanation

Step-by-step explanation:

∠1 and 43° form a straight angle = 180°, hence

∠1 = 180° - 43° = 137°

∠2 = 43° ( vertical to 43° )

∠3 = 137° ( vertical to ∠1 )

Find the midpoint of the segment with the given endpoints (5,-9) and (-2,-2)

QveST [7]

Another way to solve this is to use the Midpoint Formula. The midpoint of a segment joining points $(x_1,y_1)$ and $(x_2,y_2)$ is

$\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} \right)$

So the midpoint of your segment is

$\left(\frac{5+(-2)}{2},\frac{-9+(-2)}{2}\right) = \left(\frac{3}{2},-\frac{11}{2} \right)$

Perhaps it helps to see that the x-coordinate of the midpoint is just the average of the x-coordinates of the points. Ditto for the y-coordinate of the midpoint; just average the y's.

Please help on question 12 or 13 as soon as possible

Anna007 [38]

Answer:

to know the summation of angles: (n-2)*180

here (n) represent numbers of sides

12)we have 5 sides (n=5)

(5-2)*180=540

x=540-(105+135+92+87)=121

13)we have 8 sides (n=8)

(8-2)*180=1080

x=1080-(116+158+141+124+136+132+129)=144

I hope it will help

2r+2s=50<br> Please look at the picture

lidiya [134]

2r + 2s = 50

2r - s = 17

-----------subtract

3s = 33

s = 11

2r - s = 17

2r - 11 = 17

2r = 28

r = 14

so r = 14 and s = 11

answer is C. r = 14, s = 11
