Answer:
y=6x+-6
Step-by-step explanation:
7x10x2 basically the opposite the expression
a)
30.65^2/(2*5.15)=91.2061
d=91.2061
b)i)90
ii) Mathswatch is critical of anything apart from it's system so I dont know what the answer is for this one

Angles of rotation that would not map the shape on itself
Side of a nonagon is:
and a complete rotation is:
To start with, we calculate a possible angle of each rotation:
This is calculated by dividing the complete rotation by number of sides
The question lacks option; so, it's difficult to give a specific answer.
However, I'll give a generalized answer
For the nonagon to map on itself, the angle must be a multiple of the calculated angle of rotation (40)
i.e.
<em>Any angle different from the above listed angles (or any other multiple of 40 not listed above) answers the question.</em>
