Answer:
6/3 or 2?
Step-by-step explanation:
i am not completely sure though. I went purely based off of MN/RS, which gave me the ratio 6/3. That also equals 2.
Answer:

Step-by-step explanation:
GIVEN: Daniel invests
in a retirement account with a fixed annual interest rate of
compounded
times per year.
TO FIND: What will the account balance be after
years
SOLUTION:
Amount invested by Daniel 
Annual interest rate
Total amount generated by compound interest is 
Here Principle amount 
rate of interest 
number of times compounding done in a year 
total duration of time 
putting values we get
=


Hence the total balance after
will be 
The rise would have to be 12.
This is because in order to be "Similar" triangles the sides need to be proportionate.
(1/3 = 4/12)
Answer:
48º
Step-by-step explanation:
Answer:
3) 16.2
Step-by-step explanation:
The supplement to the 115° angle on the right is 65°, the same as the angle at upper left. The vertical angles at C are the same measure, so this tells you that the two triangles FCB and ACD are similar by the AA similarity postulate. That being the case, corresponding sides are proportional:
CB/CD = CF/CA
CB = CD·CF/CA = 7.2·21.6/9.6
CB = 16.2
_____
When given two "point-to-point" triangles like this, quite often there is some sort of similarity relationship involved. First, you need to figure out what it is; then you need to make use of it as needed to answer the question being asked.
