Answer:
Step-by-step explanation:
(x, y) --> (x + 5, y - 1)
A(3, -1) --> A'(3 + 5, -1 - 1) --> A'(8, -2)
B(6, 1) --> B'(6 + 5, 1 -1) --> B'(11, 0)
C(2, 4) --> C'(2 + 5, 4 - 1) --> C'(7, 3)
D(-1, 3) --> D'(-1 + 5, 3 - 1) --> D'(4, 2)
The second part = 1
the second part could be written sin²x.(1/sin²x), since cscx =1/sinx
hence 1 = 1
Remember that things like this, always need to add up to 180°.
