Estimate the angular diameter of your thumb, held at arm's length.
DochEvi [55]
Well, this depends on the length of your outstretched arm from the joint of your shoulder to the joint of your thumb finger. Mine is 21 inches long. My thumb is 2.5 inches long. The angular diameter can be determined using the trigonometric functions. We can use the tangent function

tan θ = opposite side/adjacent side = thumb's length/shoulder-to-finger length
tan θ = 2.5 in/21 in
θ = 6.79°

The price of a notebook is 20% less than the price of a book. By what percent is the price of the book higher than the price of
TiliK225 [7]

The price of the book is 125% higher than the price of the notebook if the price of a notebook is 20% less than the price of a book.

<h3>What is the percentage?</h3>

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

Let x is the price of the book

And y is the price of the notebook,

Then,

y = x- 0.20x = 0.80x

x = (1/0.80)y

x = 1.25y

So x is 1.25 or 125% higher than the, y

Thus, the price of the book is 125% higher than the price of the notebook if the price of a notebook is 20% less than the price of a book.
