Answer: 90 degrees counterclockwise and 270 degrees clockwise are the same things and you need to use the same formula for both
Step-by-step explanation:We swap the value of x and y and negate the value of y. So the value of x becomes the value of y and value of y becomes the value of x. so the formula is:
(x, y) –> (-y, x)
Before Rotation After Rotation
(x, y) (-y, x)

look at the photo. top angle is 2x+6 bottom angle is 3x-25 and other angle is y. find the values of x and y
Step-by-step explanation:
We know that,
sum of all angles in a triangle measures 180°
Then,
(2x+6)+(3x-25)+y= 180°
2x+3x+y=180-6+25
5x+y=199°
x+y=199/5
=39.8
I know only upto this

Angle A and angle B are supplementary. The measure of angle B is 82.5.
What is the measure of angle A, in degrees?
Answer:
Angle A = 97.5º
Step-by-step explanation:
Supplmentary means 2 angles that equal 180º. So we already have 1 angle, so now all we have to do is subtract 82.5 from 180.
180 - 82.5 = 97.5
Angle A and angle B are supplementary. Then the measure of the angle A will be 97.5°.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Angle A and angle B are supplementary. The measure of angle B is 82.5°.
Then the equation is given as,
∠A + ∠B = 180°
Simplify the equation, then the measure of the angle A will be calculated as,
∠A + 82.5° = 180°
∠A = 180° - 82.5°
∠A = 97.5°
Angle A and angle B are supplementary. Then the measure of the angle A will be 97.5°.

What is the slope of the line that passes through the points (5,11) and (14,-10)
Answer:
the picture has the answer on it
Step-by-step explanation:
The slope of the straight line that passes through the points (5,11) and (14,-10) is [tex]\frac{-7}{3}[/tex].
What is a straight line?''A straight line is an endless one-dimensional figure that has no width. A straight line is a combination of endless points joined on both sides of a point.''
Given, two points are (5, 11) and (14, -10).
Let, the line that passes through both these points has a slope = m.
Where, m = [tex]\frac{y_2 - y_{1} }{x_2- x_{1} }[/tex].
Here, (y₂ - y₁) = Change in the value of y.
(x2 - x₁) = Change in the value of y.
Therefore, [tex]\frac{y_2 - y_{1} }{x_2- x_{1} }[/tex] = [tex]\frac{-10 - 11}{14 - 5}[/tex] = [tex]\frac{-21}{9}[/tex] = [tex]\frac{-7}{3}[/tex]
Hence, slope of the straight line is [tex]\frac{-7}{3}[/tex].

A football team carried out a report to see the impact of stretching on preventing injury. Of the 50 footballers in the squad 32 stretch regularly. Of those who stretch, 4 got injured last year. There was a total of 19 injured players last year.
The results can be presented in a frequency tree. What fraction of players who don't stretch get injured?
Using proportions, it is found that the fraction of players who don't stretch that get injured is: [tex]\frac{5}{6}[/tex]
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
From the data given, there are 50 - 32 = 18 footballers who do not stretch regularly, and of those 19 - 4 = 15 stretched, hence the fraction of players who don't stretch that get injured is:
[tex]f = \frac{15}{18} = \frac{5}{6}[/tex]
