n = -1

Step-by-step explanation:

First distribute the -4

15-4n+8=27

-4n+23=27

Subtract 23 from each side

-4n=4

Divide each side by -4

n=-1

n= -1

Step-by-step explanation:

15-4(n-2)=27 do the () first

15-4n+8=27  subtract 15 and 8 from both sides to get the -4n alone

-4n= 4  divide by -4

n= -1

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
