If we have a line, and the endpoints are(x₁,y₁) and (x₂,y₂), the midpoint will be:( (x₁+x₂)/2 , (y₁+y₂)/2 );
Data:
Endpoint₁: (2,-3)
Midpoint: (6,6)
Therefore:
(2+x₂)/2=6
2+x₂=12
x₂=12-2
x₂=10
(-3+y₂)/2=6
-3+y₂=12
y₂=12+3
y₂=15
Answer; the other endpoint of a line will be (10,15)
Answer:
uhhh... why dont you check my work lol
Step-by-step explanation:
y = -15/18x + b
-1 = -15/18 (6) + b
-1 = 5 + b
-6 = b
check your work:
14 = -15/18(-12) - 6
14 = 10 - 6
14 = 4
Decrease by 6% = 100 - 6 = 94
Increase this by 19%
= 19/100 x 94
= 17.86
94 + 17.86 = 111.86
\ 100 = 1.1186
So a straight line equals 180 degrees so you need to subtract the 69 degrees from 180 to get 111 degrees
You then need to subtract the 1 from 111 to get 110
Now the missing angle is
5x=110
You then divide 110 by 5 to get 22
X=22
