What is the measure if each interior angle of a 15-gon
olya-2409 [2.1K]

Answer:

  • The sum of the interior angles of the 15-gon =\:2340^0
  • Each interior angle of the regular polygon =\:156^0

Step-by-step explanation:

As we know that

In any convex polygon, if we may start at one vertex and draw the diagonals to all the other vertices, we would form triangles,

The number of triangles thus formed would always  2  LESS than the number of sides.

As

  • The sum of measure of the angles of any triangle is 180°.

Thus,

The sum of the interior angles of the 15-gon will be:

13\:\times\:180\:=\:2340^0

Also

15-gon is regular, it means this total 2340^0 is shared in equal proportion among the 15 interior angles.

And

Each interior angle of the regular polygon will be:  \frac{2340^{0} }{15}=156^{0}

Therefore, we conclude that:

  • The sum of the interior angles of the 15-gon =\:2340^0
  • Each interior angle of the regular polygon =\:156^0

Keywords: regular polygon, 15-gon, triangle

Find the area of a rectangle with a width of x3 + 5x - 9 and a length of x2 + 8.
Drupady [299]

Answer:

A = x⁵ + 13x³ - 9x² + 40x - 72  

Step-by-step explanation:

The formula for the area of a rectangle is length X width, or A = lw.

Substitute the equations for the sides into the formula:

A = lw

A = (x² + 8)(x³ + 5x - 9)      <= use the distributive property

A = x⁵ + 5x³ -9x² + 8x³ + 40x - 72   <= collect like terms

A = x⁵ + 13x³ - 9x² + 40x - 72

Wewaii [24]

Answer:

If 18.2% of the 378 milliliters of solution is acid, 0.182(378) ml of the solution is acid. Multiplying this out, our final answer is 68.8 ml of the solution is acid.
