Answer:
No, it is not a right triangle.
Step-by-step explanation:
The simplest way to determine is testing out the numbers with Pythagorian theorem.
If it complies with the theorem, it is a right triangle.
let's assume c = 28, b = 21, and a = 20
the longest side is the hypotenuse so side c (28 in) will be the hypotenuse.
According to the Pythagorian theorem, the square of the length of hypotenuse must equal to the sum of squares of other two sides.
check:
c^2 = 28^2 = 784
a^2 + b^2 = 21^2 + 20^2 = 841
because c^2 is not equal to a^2 + b^2, the triangle is not a right triangle.
I would love to help you but I'm not at home rn basically, divide the price by amount. ex: ($)price/amount(fl oz) . do it for both store and round to thousandths and the one with the less price is the best deal. so... I apparently have some time to solve this for you, so let me begin :) just to give you an idea, I'll solve the grocery one for you! 2/64 = 0.03125 = $0.0313 per Fl Oz. solve the next one with the equation and compare to see which is lower. Explaining part, stating that the one has lower price will do.
