Answer:
x = y = 2√2
Step-by-step explanation:
Find the diagram attached
To get the unknown side x and y, we need to use the SOH CAH TOA identity
Opposite side = x
Adjacent = y
Hypotenuse = 4
Sin theta = opposite/hypotenuse
sin 45 = x/4
x = 4 sin 45
x = 4 * 1/√2
x = 4 * 1/√2 * √2/√2
x = 4 * √2/√4
x = 4 * √2/2
x = 2√2
Similarly;
cos theta = adjacent/hypotenuse
cos 45 = y/4
y = 4cos45
y = 4 * 1/√2
y = 4 * 1/√2 * √2/√2
y = 4 * √2/√4
y = 4 * √2/2
y = 2√2
Answer:
option 4: The line x = 2 is not included in the solution region is the correct option.
Step-by-step explanation:
Given the inequality
x > 2
It is clear that the given inequality is in the simple form which indicates that x is greater than 2.
Please check the attached graph.
As x is greater than 2, thus a dashed line at x = 2 on the graph indicate indicates that x = 2 is not included in the solution region.
- <em>Please remember that inequalities that use < or > symbols are drawn with a dashed line in order to display that line is not included in the region.</em>
Thus, the solution to the inequality is:
The solution indicates that that the value of x will be greater than 2.
Please check the attached graph.
A dashed line at x = 2 on the graph indicates that x = 2 is not included in the solution region.
Hence, option 4: The line x = 2 is not included in the solution region is the correct option.
