Answer:
Rounding x = 5.52
Step-by-step explanation:
2.1x - 3.6 = 8
Add 3.6 to each side
2.1x - 3.6+3.6 = 8+3.6
2.1x = 11.6
Divide each side by 2.1
2.1x/2.1 = 11.6/2.1
x =5.523809524
Rounding x = 5.52

Problem 4
a)
MR = AG is a true statement because MARG is an isosceles trapezoid. The diagonals of any isosceles trapezoid are always the same length.
-------------------------
b)
MA = GR is false. Parallel sides in a trapezoid are never congruent (otherwise you'll have a parallelogram).
-------------------------
c)
MR and AG do NOT bisect each other. The diagonals bisect each other only if you had a parallelogram.
=================================================
Problem 5
a)
LC = AJ (nonparallel sides of isosceles trapezoid are always the same length)
x^2 = 25
x = sqrt(25)
<h3>x = 5</h3>
-------------------------
b)
LU = 25
UC = 25 because point U cuts LC in half
LC = LU+UC = 25+25 = 50
AJ = LC = 50 (nonparallel sides of isosceles trapezoid are always the same length)
AS = (1/2)*AJ
AS = (1/2)*50
<h3>AS = 25</h3>
-------------------------
c)
angle LCA = 71
angle CAJ = 71 (base angles of isosceles trapezoid are always congruent)
(angleAJL)+(angleCAJ) = 180
(angleAJL)+(71) = 180
angle AJL = 180-71
<h3>angle AJL = 109 </h3>
