For each of the isosceles triangles the ratio of the length of one of hte congruent sides to the length of the base 1.3 tell the length of one side of the cotagon to the nearest 0.1 inch

Also
David says that a regular octagon is composed of eight isosceles triangles, so he suggests that they draw the four lines of symmetry and mark off the triangles. Draw a line to show where to make one of hte cuts. Give the angle measures for the isosceles triangles.

answer: y=0 if that is what u r looking for

step-by-step explanation:

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
