- AC is congruent to itself
- AC bisects angle BAD, so that angles BAC and DAC are congruent
- Both angles B and D are right angles, so they are congruent
This means triangles BAC and DAC are a pair of angle-angle-side triangles, so they are congruent to one another. Corresponding parts of congruent triangles are congruent, so the line segments BC and DC are congruent and have the same length.
Then
The number expressed as a decimal is 0.36
Step-by-step explanation:
First of all, we have to write the ratio between the number of songs from Josiah's favorite band and the total number of songs.
We have:
# of songs of his favorite band = 16
# of total songs = 44
Therefore, the fraction is:
Now we have to express this as a decimal. First of all, we simplify the fraction, by dividing each number by 4, and we get:
Now in order to write this as a decimal, we just use the calculator and we divide 4 by 11, and we get:
which is a periodic number, so we approximate to
