Answer:
Step-by-step explanation:
SSS (Side-Side-Side) Postulate can be used to prove the two triangles congruent.
<u>Here's why:</u>
Whole figure is a parallelogram which means that opposite sides are parallel and equal (or congruent).
So, Two of the sides can be proved congruent by that way.
The third side is common in both of the triangles which means that the third side is also congruent.
Hence, the two triangles are congruent by SSS postulate.
Hope this helped!

Let's say Bailey takes "b" days to paint it.
and Andrew takes "a" days to paint the same house.
now, Andrew is 6 times faster than Bailey, therefore, if Andrew takes "a" days to do it, Bailey takes then "6a" days, or b = 6a.
now, the year they worked together, they finished it in 7 days.
so, after 1 day then, they have only done 1/7 of the whole work.
and Andrew for one day, has done 1/a of the house, whilst Bailey has done 1/b of the house or 1/(6a).

Answer:
x = 7.5
Step-by-step explanation:
Given that BE is parallel to CD and intersects the 2 other sides, then it divides the 2 sides in proportion, that is
=
, substitute values
=
( cross- multiply )
8x = 60 ( divide both sides by 8 )
x = 7.5
