Can't see the diagram, but this looks like a very common question I have seen many times, so
16. Essay question
If you put the same thing just try to word it differently, you're welcome. <3
My answer:
An isosceles triangle is a triangle that has at least two equal sides and because this is an isosceles triangle, 8x -10 = 6x.
8x - 10 =6x
8x - 6x = 10
2x = 10
x = 5.
17. Essay question
My answer:
(x - p)² + ( y - q )² = r², p and q are the coordinates of the center of the circle.
The position of the source is (- 6, - 4)
An the range is r² = 36 ⇒ r = 6
18. Essay question
My answer:
A. O = ((px + qx) /2, (py + qy) /2) = ((-10 + 4) /2, (-2 + 6) /2) = (-3, 2)
There is the actual test answers hope one day someone doesn't get trolled 😭😭😭😭

Only responding to the essay questions... Aiko's answer for #2 is correct, and I don't understand what's going on question #3 so I'll explain it.
Essay Question #1:
Part A:
Finding x is pretty easy. You just need to remember that a full circle is 360 degrees. Put what you're given together and you get:
(8x-10)+(6x)+(10x+10)=360
Simplify and you get x
Part B:
Use the inscribed angles theorem: An inscribed angle is half the size of its arc. So basically Angle _ = 1/2 (Size of arc). Reminder to substitute x (Sorry I can't give full answers. I'm scared of being caught T^T)
Essay Question #2:
Just look at Aiko, they've got the answer
Essay Question #3:
Part A
Use the midpoint formula, and that gets you the center (if you don't remember the midpoint formula, just use google or something)
Part B
Use the distance formula with one of the endpoints and the center (again if you don't remember just use google)
Part C
Just input the variables you've found into the circle equation (google)

(I gave the first few words of the question just incase our tests are not the same you can mix and match the answers to get 100% I got 12 out of 15 using the answers and now I'm giving the 100% answers to my test) [also sorry for sloppy formating]
If AB=6 abd AO=11.7 || 10.0
JK, KL, LJ, are all tangent || 64
WZ and XR are diameter of circle c || 230 degrees
What is the length of AB || 42.7
Circle O is shown below || 53.5
AC is tangent to circle O at A || 58 degrees
in the circle, mBC=76 || 38
The farthest distance a satellite signal can || 42
What is the value of X || 24.0
In circle O, BC=19 and DC=35 || 45.5
The question with all the graphs || tiny circle in quadrant II (the top laft quad)
AB is tangent to Circle O at A || 72
A circle with radius x is shown below || 14.3
Circle O is shown below || 56 degrees
In the circle AB=42, BC=18 and CD=4 || 266
I assume that all the essay answers above are correct.
