Aimme is right. All the sides are obtuse. They do not equal exactly 90 degrees.
First, you would multiply $210 by 20%
This is done by converting 20% to a decimal, .2
So, 210 • .2 = 42
Then to find the sale price, you would subtract that 42 that you just got from 210,
and you get $168 as the final sale price.
The area of the shaded triangle formed as the result of the overlap is = 62.35 inches ²
<h3>Calculation of the equilateral triangle</h3>
After folding the rectangle with length of 12 inches and width of 18 inches, an equilateral triangle was formed.
An equilateral triangle is a type of triangle where by all the three sides are equal.
To determine the value of one of the sides, CB or CD is used because the folding didn't affect these sides.
Using the formula for the area of an equilateral triangle,
A = √¾ a²
a= 12 inches
A = √¾ ×12²
A = 62.35 inches ²

Answer:
The answer is 15 units hope that helps
Step-by-step explanation:
Apply pythagorean formulae here
Take the 17 as hypotenuse... And 8 as the base....
So the pythagorean formulae is
( hypotenuse) Square = (height) Square + (base) Square......
Hence put the values and the height comes as 15 units
BTW are u Indian?...
