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

4.5(4 − x ) + 36 = 202 − 2.5(3x + 28) now multiply from the paranthesis
18 -4.5x + 36 = 202 -7.5x + 70 will add the numbers
54-4.5x = 272-7.5x move x to the left and numbers to the right
7.5x-4.5x = 272-54 make the difference
3x = 218 and divide by 3
x= 72
