Answer:
Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of X.

If i'm not mistaken there is only 10 or 25 ways he could arrange them,
ie: 23,895, 28395, ect....
Answer:
k= 2
Step-by-step explanation:
First partDetermine 2 points that pass through x + 2y = 5
(i) If x = 1
x + 2y = 5
1 + 2y = 5
2y = 4
y = 2
(ii) If x = 3
x + 2y = 5
3 + 2y = 5
2y = 2
y = 1
Two points that pass through this line are (1,2) and (3,1)
Second partDetermine 2 points that pass through 3x = 15 - 6y
(i) If x = 1
3x = 15 - 6y
3(1) = 15 - 6y
3 = 15 - 6y
6y = 15 - 3
6y = 12
y = 2
(ii) If x = 3
3x = 15 - 6y
3(3) = 15 - 6y
9 = 15 - 6y
6y = 15 - 9
6y = 6
y = 1
Two points that pass through this line are (1,2) and (3,1)
BOTH OF THE LINE pass through the same two points, that means the lines are the same because they overlap. Look at the attachment.
