Jill says 12.6¯¯¯ is less than 12.63. Explain her error. P. S: The line is supposed to be over the 6

Her error is 12.6¯¯¯  being more than 12.63

Step-by-step explanation:

The bar above the 6 means repeating so 12.6¯¯¯  would be 12.666 and 12.666 is more than 12.63.

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.

answer: x=60
