A certain high school offers exactly two foreign languages, Spanish and French. 10\% of students do not take a foreign language class, and 70\% of students take exactly one foreign language class. If half of all students take a French class and 50 students take classes in both languages, how many students take a Spanish class

step-by-step explanation:

10.50 + taxes which added up to 11.50

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.
