Answer:
∠ AFE = 80°
Step-by-step explanation:
Since BD is a straight line , then
∠ AFB + ∠ AFE + ∠ EFD = 180°, that is
50° + ∠ AFE + 50° = 180°
100° + ∠ AFE = 180° ( subtract 100° from both sides )
∠ AFE = 80°
Answer:

3. 7 lines
4. (2,-8)
5. x = 15
Step-by-step explanation:
1. for translation over y=x you need to switch what is negative and what is positive
2. You add whatever number is said to be added to X and whatever number is said to be added to Y.
3. A regular heptagon has 7 equal sides so it has 7 lines of symmetry.
4. For over the x-axis you make the y negative (or if it is already negative you make it positive) you do the opposite for over the y-axis
5. When you have a mid-segment you take one side, 9 and 6, and you divide 9 by 6. You get 1.5, you then take 1.5 and multiply it by 10, that leaves you with 15
I hope I helped!
then divide 448 by 2335 B + 10
A.P is 3x+7y,8x+4y,13x+y.........
comman diffrence d=8x+4y-(3x+7y)
d=5x-3y
right answer is C.5x-3y
