Answer: 9/8

Step-by-step explanation: In this problem, we are asked to find the reciprocal of the fraction 8/9. When we are asked find the reciprocal of a fraction, we simply flip the fraction so the denominator is in the position of the numerator and the numerator is in the position of the denominator.

So if we flip 8/9, we get the improper fraction 9/8.

Find the area of each regular polygon. Round to the nearest tenth.
miskamm [114]

Given:

A regular polygon with three vertices and side 14 cm.

To find:

Area of the regular polygon.

Solution:

We know that, a regular polygon has equal sides and equal interior angles.

The given regular polygon has three equal sides, it means it is an equilateral triangle.

The area of an equilateral triangle is:

A=\dfrac{\sqrt{3}}{4}a^2

Where, a is the side length of the triangle.

Putting a=14, we get

A=\dfrac{\sqrt{3}}{4}(14)^2

A=\dfrac{\sqrt{3}}{4}(196)

A=84.87049

A\approx 84.9

Therefore, the area of given regular polygon is 84.9 cm².
