A magic square is a square array of numbers arranged so that the numbers in all rows, all columns, and the two diagonals have the same sum. Create a 3-by-3 magic square using nine of the ten numbers, 20, 21, 22, 23, 24, 25, 26, 27, 28, and 29.

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

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.
