Question

Andre is building a structure out of playing cards. Each card
is 6.3 centimeters long. He tries leaning the cards against
each other so that the angle at the top is 900. Find the
distance between the edges of the cards to the nearest tenth.

Answer 1

Andre cannot lay a card across the top of the structure because 6.3 cm<8.9 cm. He most likely cannot lay a card across the top of the structure because 6.3 cm is the distance between two consecutive peaks, and there should be some overlap for the card to stay.

Answer 2

How did i find the distance

Answer 3

It forms a new triangle of the exact same measurements in the middle
