The system:
- 12 c + 3 d = 6
- 3 c + 6 d = - 9
----------------------
The 1st equation:
- 12 c = - 3 d + 6 / * ( - 1) ( multiple both sides by -1 )
12 c = 3 d - 6 / : 12 ( divide both sides by 12 )
c = d / 4 - 1/2
Answer:
C ) c = 1/4 d - 1/2
<span>the smaller angle is 2x = 2 times 18 = 36 degrees.
the larger angle is 3x = 3x = 3 * 18 = 54 degrees.

I tried to do my best to solve and show work. If you need an explanation just leave a comment :)
Answer:
15+1x+1y
Step-by-step explanation:
you can add 9+6 so you do that and that equals 15
Then X and Y each represent 1 so
the answer would be 15+1x+1y
