A. Given (This is part of the original problem)
b. Supplementary angles form 180 degrees (The definition of supplementary angles is that two or more angles have a sum of 180 degrees. DC is a straight line and has a measure of 180 degrees)
c. Substitution (Given the two previous statements, they are each equal to 180 degrees. Since 180=180 then you can substitute the angles in the equation.)
d. Subtraction (m<2 is being subtracted)
e. Subtraction postulate (Since the same quantity was being subtracted from each side of the equation, they are still equal)
D is you answer Have a wonderful day !
-12 is a rational number, an integer, a real number, and a whole number.
Answer:
100°
Step-by-step explanation:
all four angles added together total 360°
x = 360° - 60° - 110° - 90°
x = 100°
Answer:
x = 0, 
, 3
Step-by-step explanation:
Hey there!
<em />
<em>Step 1: Regroup terms.</em>
2x(6x + 1) (3x - 9) = 0
<em>Step 2: Solve for x.</em>
x = 0, , 3
