2. LEE MIDDLE SCHOOL ALLOWS STUDENTS oice that you TO EITHER BRING OR BUY THEIR LUNCH. YESTERDAY, 345 STUDENTS DECIDED TO BRING THEIR LUNCH WHILE 405 STUDENTS DECIDED TO BUY THEIR LUNCH. WHAT PERCENT OF THE STUDENTS DECIDED TO BRING THEIR LUNCH YESTERDAY?

the answer will be

a. is correct

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
