According to the secant-tangent theorem, we have the following expression:
Now, we solve for <em>x</em>.
Then, we use the quadratic formula:
Where a = 1, b = 6, and c = -315.

<h3>Given:</h3>
- P= $50,000
- R= 10%
- T= 5 years
- P= Principal amount
- R= Rate of interest
- T= Time period
Let's substitute according to the formula.
<em>A=</em><em> </em><em>$80525.5</em>
Now, we can find the interest paid
We'll have to deduct the total amount from the principal amount.
Let's substitute according to the formula.
<em>I=</em><em> </em><em>$30525.5</em>
