In how many ways can u answer a 12 question true- false test if u answer each question with either true or false

24 ways

because if there are 2 answers per question 2 times 12 is 24

hope this helps

i think it is 70

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
