We have to relate the angles of the trapezoid in order to find the measure of BAD.
Given:
Then
The angles are congruent because if AD and BC are congruent, and the lines are parallel, they sides will form the same angles.
Also, as the segment AD is "cut" by two parallel lines, the angles BAD and ADC are consecutive interior angles and are, therefore, supplementary.
Then, we can write:
Now, with the value of x, we can calculate the measure of BAD as:
Answer: the measure of BAD is 74°.
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.
