~kites have adjacent sides equal~
x = 3x-12
move 3x to the other side as a negative number
-2x = -12
divide both sides by -2
-12 divided by -2 is 6
so, x is equal to 6
but, we aren't done yet because the questions asks for the value of angle b
substitute the value we found into the equation for angle b
3(6)-12
36-12
24
so, angle b has a value of 24 degrees
Step-by-step explanation:
A circle has 360 degrees so 360/18= 20
For the 2nd question: 360/5=72
Answer: True
Step-by-step explanation: The left side 3.6 is greater than the right side 1, which means that the given statement is always true.
I hope this helps you out!
Answer:
20x²+180x + 405
Step-by-step explanation:
Follow PEMDAS to know what you do first
square (2x + 9) by foiling
(2x+9) (2x + 9)
= 4x²+ 36x + 81
Multiply by 5
20x²+180x + 405
A number that is not a whole number.
