40% of the student in a class are female. if there are 10 females in the class, how many males are there in the class

this shouldn't be that hard, if 10 is equal to 40% then you can tell that there are 15 men.

Final 15

What we were given:

40% of the student in a class are female. if there are 10 females in the class, how many males are there in the class

15 males

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.
