The cover of a textbook is 9x11 inches. what is the ratio of its base to its height? does the cover of the textbook represent a golden triangle?

Hello! By "golden triangle," you likely meant "golden rectangle."

The length of a golden rectangle is appox 1.618 the width.

On the other hand, the dimensions 9 by 11 boil down to 1.222; this means that the length is approx. 1.222 times the width.

No, the textbook does not have the proportions of a golden rectangle.

no one knows lol

step-by-step explanation:

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
