You have a bag with 12 balls, 4 yellow and 8 blue. You pull one ball at random and put it back before you pull the next one. Draw a tree diagram and calculate P (1 yellow, 2 blue).

1/800 is the right answer

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

b, i believe, but not sure.
