Answer:
liner
Step-by-step explanation:
Answer:
A) mJK = 21
B) mJNM = 159º
C) mKL = 159
D) mJKM = 201
E) mMKL = 339
Step-by-step explanation:
Circle = 360º
360º - 21º = 339º (what all missing angles have to add up to)
Assuming that:
JNL and KNM are both 180º angles
KJ and JM are supplementary as well as KL and LM
If we subtract 21º from 180º we get 159º which is both LM and KL
If we add 21º to 180º we get 201º which is both JKM and LMK
By subtracting 21º from 360º we know that MKL is 339ª
if we add 159º + 159º + 21º we get 339º which proves that those are our missing angles becuase our missing angles must make a total of 339º
Sorry that took so long I was pulling out all my notes from last year to make sure I was doing this right ^^;
Answer:
The scale factor would be 1/3
Step-by-step explanation:
Find the scale factor by comparing the heights of the preimage and image.
The height of the image is 4 and the height of the preimage is 12
So the scale factor is 4/12, which can be simplified to 1/3
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- 4x + 8y = 20
- -4x + 2y = -30
<u>Adding</u><u> the</u><u> equations</u><u> </u><u>:</u><u>-</u><u> </u>
10y = -10
y = -1
<u>Put </u><u>it </u><u>(</u><u>i)</u><u> </u><u>:</u><u>-</u><u> </u>
4x - 8 = 20
4x = 20 + 8
4x = 28
x = 28/4
x = 7
