Write a decimal between the numbers7.23 and 7.86

You can write any number between 7.23 and 7.86 for example:

7.24 is between 7.23 and 7.86 so any of the viable answers are:

7.24 through 7.85

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
