Prove that for all n e z, n is even iff n can be written in one of the forms 4k or 4k + 2 for integer k. (hint: for one of the directions, d 4) use the quotient-remainder theorem with some

what? that isnt a question

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
