Answer:
90° CCW
Step-by-step explanation:
The slope of BA is -1/3. The slope of BA' is 3, so the slopes are opposite reciprocals of one another. These segments are perpendicular, meaning the angle between them is 90°.
Point A' has been rotated 90° CCW about point B.
Answer:
x = 8, y = 8√2
Step-by-step explanation:
x = 8
y = 8(√2) = 8√2
Step-by-step explanation:
4:3
4+3=7
4x + 3x= 7x
7x is the total sq.cm which is 300
7x= 300
x= 300/7
= 42.8
length= 4x
= 4 × 42.8
= 171.42
breadth= 3x
= 3 × 42.8
= 128.4
