Answer: the answer is -2n + 4
Answer:
The answer is y=5
Step-by-step explanation:
9x=-18
x=-2
-2+9y=43
9y=45
y=5
First, find the value of x. Note that the angles x, 0.5x and 3x sum up to 4.5x, and that this sum has the value 180 degrees. Solving this equation for x, we get x = 40 degrees.
Now, 0.5x and 0.5y are vertical angles, and thus x = y. So, with x being 40 degrees, y = 40 degrees.
Answer: 3.14 *16.8*16.8*16.9=14977.3478
14977.3478= 14,977.35
1 and 2 are right because one has adjacent. 2 vertical angles. Vertical angles mean the same plane and adjacent means two sides of an X.
