< ABE is the whole angle=measures 2b.
<span>< ABF is a portion of <ABE = measure 7b - 24. </span>
measure of the whole angle and a part of the angle
<span>Angle EBF = Angle ABE - Angle ABF
=</span>7b - 24-2b
=6b-24
hope this helps
If you graph the three given points, you can see that the vertex (h,k) is (-1,3).
Equation of a quadratic function is: y = a(x - h)² + k
Plug in the vertex and one of the points (I chose (0,1)) and solve for "a".
1 = a(0 + 1)² + 3
-2 = a
Answer: f(x) = -2(x +1)² + 3

Answer: 33</h3>
=======================================================
Explanation:
The information that m || n is not needed or used, so I'm not sure why your teacher put that in there.
The angles shown are a linear pair. They are adjacent and they are supplementary. They form a straight angle.
Supplementary angles add to 180.
(x-17)+(5x-1) = 180
x-17+5x-1 = 180
(x+5x)+(-17-1) = 180
6x-18 = 180
6x = 180+18
6x = 198
x = 198/6
x = 33
---------
Extra info:
if x = 33, then,
- x-17 = 33-17 = 16
- 5x-1 = 5*33-1 = 165-1 = 164
Adding the angles gives 16+164 = 180 which helps confirm our answer.
