Answer:
12√3
Step-by-step explanation:
432 is 144 times 3 , and 144 can be written as 12 to the power 2. So, the 144 can just be pulled outside of the radical sign, as a 12 , and the other factor, the 3 , just stays inside of the radical sign.
Or, √432 = 12 √3
from your previous posting, you saw that y = 18, that means that the angle 2y + 6 is really 2(18) + 6 or namely 36 + 6 = 42°.
vertical angles, or namely angles across from each other at a junction, are always equal, so if 2y + 6 is 42°, then 8y - 102 is also 42°.
let's recall that a circle has a total of 360°, if we subtract those two vertical angles from a full circle, that'd be 360 - 42 - 42 = 276.
the angle 3x and its vertical angle twin, each take half of that 276° leftover, namely 276 ÷ 2 = 138°.
so now we know that 3x = 138, 

The inequality that express the relationship between -2 and -5 is : " greater than " or " > "

Answer: Its hard to explain, so I'll just give you the answer (47 degrees)
