30/54 in simplest form is 5/9
5÷3=length
5 is the length of the banner and you need to know the length. You already know that the length is 1/3 of the width (5).
1.7 feet
The value of x from the given circle is 12
<h3>Circle theorem</h3>
Angle at the vertex of the circle is half the angle at its intercepted arc.
From the given circle;
The measure of <DEF = 80/2 = 4x -8
Equate both angles
4x - 8 = 80/2
Add 8 to both sides
4x - 8 + 8 = 40 + 8
4x = 48
x =12
Hence the value of x from the given circle is 12

Answer:
288 tiles
Step-by-step explanation:
16×18= 288 so he needs 288 square tiles
This is a difference of perfect squares which is of the form:
(a^2-b^2)
And which always factors to:
(a-b)(a+b)
In this case:
(5x-8)(5x+8)
