The first angle is 130.5 degrees and the second angle is 49.5 degrees. They are supplementary angles since their sum is 180 degrees.
In this problem, we're given that two angles are supplementary, which means the sum of their measures is 180 degrees. If we call the second angle x, then the first angle is described as 3x - 18, as it is 18 degrees less than three times the measure of the second angle.
We can create an equation based on this information: x + (3x - 18) = 180. Solving this equation gives us x = 49.5. That means the second angle is 49.5 degrees.
Substitute x with 49.5 degrees into the expression for the first angle: 3 * 49.5 - 18 = 130.5. Thus, the first angle is 130.5 degrees and the second angle is 49.5 degrees. Both angles sum up to 180 degrees, confirming that they are supplementary.

The graph for the function f(x) = 5 - 5x² is shown in the figure below.
The given function is f(x) = 5 - 5x²
Consider x = {-1, 0, 1}
When x = -1
f(-1) = 5 - 5(-1)²
= 5 - 5
= 0
∴ (-1, 0)
When x = 0
f(0) = 5 - 5(0)²
= 5 -0
= 5
∴ (0, 5)
When x = 1
f(1) = 5 - 5(1)²
= 5 - 5
= 0
∴ (1, 0)
So, the coordinatepoints are (-1, 0), (0, 5), and (1, 0)
Plotting these points in the graph.
Connecting those points gives a curve shown in the figure below.

Answer:
18
Step-by-step explanation:
The middle number of the sequence us the median
The diameter of Titan
The diameter of Neptune
The diameter of the Titan is more than Pluto and the diameter of the Titan is less than Neptune.
Diameter of Pluto < Diameter of Titan < Diameter of Neptune
It is the order of the numbers in which a smaller number comes first and then followed by the next number and then the last number will be the biggestone.
The planets are given below.
Pluto, Titan, and Neptune.
We know that the diameter of the planets will be
Pluto = 2376.6
Titan = 5149.5
Neptune = 49244
Then the diameters are in ascending order is given as
The diameter of Pluto < The diameter of Titan < The diameter of Neptune
More about the ascending order link is given below.
