Which statement about this parallelogram and rhombus is true?

a.
both have 2 pairs of parallel sides, but the parallelogram has 2 pairs of congruent sides and the rhombus has 4 congruent sides.

b.
both have 2 pairs of parallel sides, but the rhombus has 2 pairs of congruent sides and the paralleogram has 4 congruent sides.

c.
both have 4 congruent angles, but the parallelogram has 2 pairs of congruent sides and the rhombus has 4 congruent sides.

d.
both have 4 congruent angles, but the rhombus has 2 pairs of congruent sides and the quadrilateral has 4 congruent sides.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
