The diagram from problem 1 is missing. So I'll only answer problem 2.
Let x be the length of the unknown segment (labeled with a question mark)
If you add the parallel bases of any trapezoid, then divide by 2, you'll get the length of the midsegment.
So,
(base1+base2)/2 = midsegment
(x+2.92)/2 = 3.98
x+2.92 = 3.98*2 .... multiply both sides by 2
x+2.92 = 7.96
x = 7.96-2.92 ...... subtract 2.92 from both sides
x = 5.04

Answer:
circumcenter
Step-by-step explanation:
If points Q, R, S are on a circle, the sides of that triangle are chords of the circle. The point where the perpendicular bisectors of those chords meet is the center of that circumcircle. It is named the circumcenter.

Answer:
y = 5x - 7
Step-by-step explanation:
We can make an equation for the perpendicular line by swapping the x- and y-coefficients, negating one of them. Then we can use that form with the given point to see what the constant is.
10x -2y = ...
Removing a common factor of 2 gives ...
5x -y = 5(2) -(3) = 7 . . . . using (x, y) = (2, 3), we can find the constant
Solving for y, we get ...
5x -7 = y . . . add y-7
y = 5x -7 . . . write in the desired form
