For example, 1/2 in not an equivalent ratio
You can use the trig ratios. Draw a diagram to see which one is appropriate.
Tan would be used.
Tan29=x/20
20Tan29=x
Put this into your calculator and see what you get

Simple Interest Rate Formula: 
- A is final amount
- P is principle (initial) amount
- r is rate
- t is time (in years)
Step-by-step explanation:
<u>Step 1: Define</u>
P = 7200
r = 0.75% = 0.0075
t = 5
<u>Step 2: Solve for </u><em><u>A</u></em>
- Substitute in variables [Simple Interest Rate Formula]:

- (Parenthesis) Add:

- Evaluate exponents:

- Multiply:
