In the diagram below, AB, BC and CD are three sides of a regular polygon. The polygon has 15 sides.
The length of each side is 8 cm.
The exterior angle of the polygon is x®
BRC is a right-angled triangle.
Calculate the length of BR.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

this answer is !
