Answer:
I believe the answer is D
Step-by-step explanation:
I did it by eliminating all other options
A cant be true because with a 90 degree rotation RS is going to be perpendicular to R'S', not parallel.
B can't be true because SP is a straight line and R'S' like RS wont be (rotation doesn't change the fact that it isn't a completely straight line.
Now, rotation doesn't affect the degree of an angle. so...
C can't be true because 60 degrees isnt just going to change to 80 degrees out of nowhere
but D can be true because of this rule.
I hope this helps!

Answer:
The answer to your question is b = 8.06 cm
Step-by-step explanation:
Data
hypotenuse = c = 9 cm
long leg = b = ?
short leg = a = 4 cm
Process
This is a right triangle so we must use the Pythagorean theorem to find the length of the long leg (b)
c² = a² + b²
-Solve for b²
b² = c² - a²
-Substitution
b² = 9² - 4²
-Simplification
b² = 81 - 16
b² = 65
-Result
b = 8.06 cm
Answer:
Check boxes 3, 4, 6, and 8.
Step-by-step explanation:
We have the equation:
And we want to select all equations that are perpendicular to the above equation.
Remember that perpendicular lines have slopes who are negative reciprocals of each other.
Therefore, the slope of our equations must be the negative reciprocal of -3.
The negative reciprocal of -3 is 1/3. We flipped -3 to -1/3, and then multiplied by a negative.
Therefore, any equation with a slope of 1/3 is perpendicular to our original line.
Therefore, we will check boxes 3, 4, 6, and 8.
