Answer:
A. 
and 
Step-by-step explanation:
Given:
Vertices of triangle RST are 
and 
.
Rotation is 90° about the center O(0,0). The rotation is counter-clockwise as the angle of rotation is positive.
Now, the co-ordinate rule for 90° rotation counter-clockwise is given as:
→ 
and 
values interchange their places with becoming negative when interchanged.
So, 
→ 
→ 
→ 
⇒ → 
Therefore, the image of the vertices are and .
Because there is a square at the bottom of the figure, we can say that the angle is equal to 90 degrees (x+22). Thus, the equation would be
x+22 = 90
x = 68
The value of "x" is then equal to 68
Multiply both sides by 4 to isolate the x term.
x = 5 × 4
x = 20
When you do the 25. You have to do the 0 so it would be 0.025
Answer:
These are all the same questions with one answer. 0.6 is greater than 0.571. Therefore, 3/5 is greater than 4/7 and the answer to the question "Is 3/5 greater than 4/7?" is yes.
