I need you someone to solve this and show their work. Tell me why the answer is 4.

x = 4

Step-by-step explanation:

You begin by making what is inside the brackets = 0. In other words you will somehow get 0 * brackets + 3 = 3

x - 4 = 0

x - 4 + 4 = 0 + 4

x = 4. When you make x = 4, the inside of the brackets = 0

1/2 * 0 = 0

So you are left with

3 = 0 + 3

and x has been made = 4

Do what's in the brackets before anything else.

i can't solve unless i know what the line is

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
