Answer:

x = 80, y = 100

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 7 , then

sum = 180° × 5 = 900°

Sum the interior angles and equate to 900

y + 135 + 140 + 150 + 120 + 135 + 120 = 900, that is

y + 800 = 900 ( subtract 800 from both sides )

y = 100

x and y are adjacent angles and are supplementary, that is sum to 180°

x + y = 180

x + 100 = 180 ( subtract 100 from both sides )

x = 80

Thus x = 80 and y = 100

Find the amount due if $200 is borrowed for 10 months at an APR of 16% simple interest<br> Amount =?
alisha [4.7K]

Answer

$266.66

Step-by-step explanation:

We have here ,

  • Principal = $200
  • Rate = 16%
  • Time = 10 months = 10/12 yrs.

We can use the formula of SI to calculate the SI . After adding it to principal we will get the amount .

⇒ SI = P × R × T / 100

⇒ SI = $ 200 × 16 × 10 / 12 × 100

⇒ SI = $ 26.66

Now Calculate amount as ,

⇒ A = SI + P

⇒ A = $ 200 + $ 26.66

⇒ A = $ 226.66

All the given option  are

A. If a point does not divide a segment into two congruent segments, it is not a midpoint.

.  

B. point that divides a segment into two congruent segments is a midpoint.

C. This statement is not reversible.
