. Name the congruent parts.

AB and CD

<A = <C

This is given information, but everything on this might or might not be congruent, since it has the same angles and side lengths.

It might be symmetrical along E and vertically downwards, but no garuantees since the image is a bit warped.

Step-by-step explanation:

A simple thing to remember is that the notches in the angle symbols and the sides mean that they are congruent. If a side has 2 notches, every other side that has 2 notches are congruent.

Angles and sides are not congruent of course, but angles that have the same number of notches are equivalent.

So with this in mind, we know stuff.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
