Ten balls numbered 1 to 10 are placed in a basket. if one ball is selected at random, find the probability that the number is 5 or 7.

The answer is 1/5 or 20% chance that it would be 5 or 7.

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.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
