Okay, Given that these are vertical angles with each other, we can set them equal to each other. This means our equation to find out what x is, is 

3x-3=2x+13

We now need to move like terms to each other. We can do this by adding 3 to both sides of the equation to cancel our the -3.

Our equation will now look like:
3x=2x+16

Now we will move the 2x over to the opposite side to get the 16 alone. We will need to subtract 2x from both sides.
This will leave us with

x=16. This means that we can now plug 16 in for the x value. 

This means that angle 

3(16)-3= 45 
and
2(16)+13= 45.

This means that the measurement of each angle will be 45 degrees.

3X-3=2X+13

3X-2X=13+3

X=16

If $11,000 is invested in an account for 25 years. Find the value of the investment at the end of 25 years if the interest is:
Naya [18.7K]

If $11,000 is invested, $33,000 is the value of the investment at the end of 25 years if the interest is 8% simple interest and $75,333.23 is the value of the investment at the end of 25 years if the interest is 8% compounded annually. This can be obtained by using formulas for simple interest and compound interest.

<h3>What is the formulas of simple interest and compound interest?</h3>
  • Simple interest

A = P(1 +Rt/100) , P = principle amount ,R = rate of interest, t = time(in years)

  • Compound interest (annually)

A = P(1 + R/100)^t , P = principal amount, R = rate of interest,                                t = time(in years)

   

<h3>What is the value of investment?</h3>

Given that,  

P = $11,000 , R = 8%,  t = 25 years

  • 8% simple interest

A = P(1 +Rt/100) = 11000(1+\frac{(8)(25)}{100} ) = $33,000

  • 8% compounded annually

A = P(1 + R/100)^t = 11000(1+\frac{8}{100} )^{25} = 11000(1.08 )^{25} = $75,333.23

Hence If $11,000 is invested, $33,000 is the value of the investment at the end of 25 years if the interest is 8% simple interest and $75,333.23 is the value of the investment at the end of 25 years if the interest is 8% compounded annually.
