The folds create four geometric kites. also, the 16 right triangles adjacent to the corners of the paper are all congruent, as are the 8 right triangles adjacent to the center of the paper. find the measures of all four angles of the kite labeled abcd. use the facts that ∠b ≅ ∠d and that the interior angle sum of a quadrilateral is 360°.

m∠a=90

m∠b=112.5

m∠c=45

m∠d=112.5

a) 32pie square meters

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
