The area of rhombus abcd is 72 square units. ec = 8 units and db = x – 1. what is the value of x? 9 10 14 16

The answer is ten, the second one

Solution: A rhombus abcd  whose area is 72 square units.

Diagonals ac and bd intersect each other at point e.

Also, db= x-1,

ec = 8 units, so, ac=16 units → as diagonals of rhombus bisect each other.

→Area of Rhombus = 1/2 × Product of Diagonals

→ 72 = 1/2×16×(x-1)

→144= 16 (x-1)

Dividing both sides by 16,we get

→ x-1=9

→ x=9+1

→ x=10 units

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.
