It is given in the question that

And 
can also be written as

Therefore,


That gives,

4x-2 + 7x-18 + 6x+6 = 360 degrees
combine like terms
17x-14 = 360
add 14 to both sides
17x =374
divide both sides by 17
x = 374 / 17 = 22
JL = 7x-18
replace x with 22 and calculate
7(22) - 18 = 154 -18 = 136 degrees
Answer:
the angle of x measures 16.6
Answer:
1,200 > 1,100
Step-by-step explanation:
This is because 1,183 is rounded up to the nearest hundred which is 1200 (since 8 which is the tens digit is greater than 5) and 1,145 is rounded down to the nearest hundred which is 1,100 (since 4 which is the tens digit is less than 5).
So, 1,200 > 1,100
