Hello
DEF and IKL , equilateral =>
DE = 5x-12 = 3x-4
5x-3x= -4+12
2x= 8
x=4
DE = 5x-12 = 20-12 = 8
KL = 3x+24 = 10x+3
24 -3 = 10x-3x
21 = 7x
x= 21/7 = 3
KJ = 10x+3 = 30+3 = 33
4r-3+r+7=29
5r+4=29
5r=25
r=5
The answer is B
I found the value of x to be 6 by adding the two equations together and setting them equal to 180.
2x^2+3x-5+x^2+11x-7=180
When you solve for x you get x=6
Then you plug 6 in for x in each angle. The first angle is 85 and the second is 95.

2.2=x
Answer:
D
Step-by-step explanation:
0.45-0.48 is smaller to larger so D is 45,46,47,48 so thats your answer
