A)360/6 = 60. 180-60 =120 degrees i think
b) 360/8 = 32.5. 180-32.5= 147.5 degrees i think

To calculate the exterior angle of a regular polygon, we have to divide 360 by the number of sides on the polygon
Angle a is the exterior angle on a regular hexagon, which has 6 sides.
So, to calculate the exterior angle, we use 360/6 = 60 degrees

To calculate angle b, which is an interior angle, we calculate the exterior angle and subtract it from 180. This is because angles on a straight line add up to 180 degrees

Angle b is an interior angle of an octagon, which has 8 sides. So, we use
180 - (360/8) = 180 - 45 = 135 degrees.

Hope I helped! xx

Paul is saving for a down payment to buy a house. The account earns 13% interest compound quarterly, and he wants to have $15,00

Tatiana [17]

Answer:

The principal must be = $8991.88

Step-by-step explanation:

Formula for compound interest is:

$A = P(1 + \frac{r}{n})^{nt}$

Where A is the amount after 't' years.

P is the principal amount

n is the number of times interest is compounded each year.

r is the rate of interest.

Here, we are given that:

Amount, A = $15000

Rate of interest = 13 % compounded quarterly i.e. 4 times every year

Number of times, interest is compounded each year, n = 4

Time, t = 4 years.

To find, Principal P = ?

Putting all the given values in the formula to find P.

$15000 = P(1 + \frac{13}{400})^{4\times 4}\\\Rightarrow 15000 = P(1 + 0.0325)^{16}\\\Rightarrow 15000 = P(1.0325)^{16} \\\Rightarrow 15000 = P \times 1.66817253\\\Rightarrow P = \dfrac{15000}{1.66817253}\\\Rightarrow P \approx \$8991.88$
