slamgirl [31]

Answer:

$New = -92\frac{1}{8}$

Step-by-step explanation:

Given:

$x = -75\frac{3}{4}$ --- Position

$\triangle x = -16\frac{3}{8}$ --- Change

Required

Find the new position

The new position is calculated as:

$New = x + \triangle x$

$New = -75\frac{3}{4} - 16\frac{3}{8}$

$New = -75.75 - 16.375$

$New = -92.125$

$New = -92\frac{125}{1000}$

$New = -92\frac{1}{8}$

The perimeter of the pentagon with apothem of 5cm is 28.87cm

<h3>How to calculate the perimeter of a pentagon</h3>

The sum of all the external sides of the pentagon is its perimeter.

First we need to calculate the half of one of its sides using the SOH CAH TOA

tan 30 = x/5

x = 5 tan 30

x = 2.89

One of the sides = 2(2.89) = 5.77 cm

Perimeter of th pentagon = 5(5.77) = 28.87

Hence the perimeter of the pentagon with apothem of 5cm is 28.87cm
