The answer to the question is (2,-2) d
Answer: The first one
Step-by-step explanation:
Answer:
Option A shows the image of RST after the rotation
Step-by-step explanation:
Coordinates of S=(1,3)
Coordinates of R = (-2,1)
Coordinates of T = (-1,7)
We are given that after rotation(x,y)→(y,-x)
So, The new coordinates after rotation will be :
Coordinates of S'=(3,-1)
Coordinates of R'= (1,2)
Coordinates of T'= (7,1)
These are the coordinates of triangle of Option A
So, Option A is true .
Hence Option A shows the image of RST after the rotation

Answer:
.
Step-by-step explanation:
Two angles are supplements of one another if their sum is .
Two angles are complements of one another if their sum is .
Let be the measure of the angle in question.
The supplement of this angle would be .
The complement of this angle would be .
According to the question:
.
Solve this equation for :
.
Thus, this angle would measure should .
The supplement of this angle would measure . The complement of this angle would measure .
Three times the complement of this angle would be , which is indeed greater than the supplement of this angle.
