Given:
The point is (-8,3).
To find:
The image of the given point after a rotation of 270 degrees counterclockwise about the origin.
Solution:
If a point is rotated 270 degrees counterclockwise about the origin, then the rule of rotation is:

Using this rule, we get


Therefore, the image of the given point after a rotation of 270 degrees counterclockwise about the origin is (3,8).
Answer:
l : b = 6 : 5
Step-by-step explanation:
let's assume lenght of each congruent rectangle be x
now,
Lenght of the larger rectangle =
=》3 × lenght of smaller rectangle = 3x
but it is also equal to
=》4 × width of each smaller rectangles ( b )
so, we get :-
=》4 × b = 3x
=》b = 3x / 4
so, we get width of smaller rectangle =

now, width of larger rectangle =
=》lenght of smaller rectangle + (2 × width of smaller rectangle)
=》

=》

=》

=》

now, length of larger rectangle = 3x
width of larger rectangle = 5x/2
so l : w :-
=》

=》

=》

so, required ratio of l : b = 6 : 5
A, C, and E. Both sides of the ratio has to change at the same time. If you multiply both sides by 2 you get 8:10. If you divide both sides by 2 you get 2:2.5. and if you divide by 1.5 you get 3:3.75.
Sorry if my explanation doesn't make sense
Answer:
x=45
Step-by-step explanation:
We know that this is a right isosceles triangle because it has a right angle (square) and a triangle has to add up to 180 degrees so 90+x+x=180
90+2x=180
2x=90
x=45
