The R stands for "rotation". The "O" as a small subscript means "origin" which is where the x and y axis cross. The 90 degrees means we rotate 90 degrees counterclockwise. This is equivalent to 270 degrees clockwise, but writing is not correct as we don't rotate 270 degrees counterclockwise.
Step-by-step explanation:
You need to know some geometry rules.
For example:
Angle sum of a triangle is equal to 180 degrees.
Straight line is equal to 180 degrees.
Other rules I have attached.
If you have any confusion over these I will be happy to answer your questions.
Answer:
a = -1 , b = 4 , c = 3 , d = 1
Step-by-step explanation:
The general rules of exponent:
===================================================
Given:
The right hand side = (-xy)³ (xz) = (-1)³ x³ y³ x z = (-1) x⁴ y³ z
Comparing the right hand side with the left hand side
∴ a = -1
∴ b = 4
∴ c = 3
∴ d = 1
